The names of the devices used here are called drive1-2 and rdrive1-2 but can be defined using other names. To follow convention, the unbuffered device should begin with the letter "r" which stands for raw device. o ADMIN> makefs /dev/rdrive(X) Once the device has been defined, a filesystem is created using the makefs command. o Verify that the drive has been correctly partitioned by using the "space" command. The number of blocks returned should reflect the size of the hard disk installed.

These terminals are usually connected to a modem. This should not be viewed as a problem since system security has not been violated; to log on to the system will still require an Operator ID and Password (if required). The reason that 'admin' shows logged in is that when an or ^C is entered at the Escape prompt, admin is called to execute the '/bin/login' command. This is the command that prompts for the operator ID and password. In some cases, a modem will produce oneof these characters which in turn calls admin to run '/bin/login'. If this is a problem for your customer, the work around is to turn off the modem during system boot. ORIGINATOR: W.

PROBLEM: At power on, as part of each controller self test, data output from Serial Communication Controller (SCC) ICs were internally looped back. The SCC data out-puts were disabled from going to the serial line by hardware. The disabling action was causing a NULL character inadvertently sent out to the line which, on DIABLO interface type printers would cause a garbage character (`?') printed.

This condition is generated when an error occurs and the error handling logic causes a tight program loop. Since the loop is so tight, the ESCAPE is not seen and the condition gives the appearance that the terminal is locked.

Another example would be: 00100 SETERR 00100 200 X=I/B Where B=0 (which sets an invalid divide by 0 condition) Presently there is no work around for this condition. If your program gets in this condition use the 'ps -a' command to find the task executing and then use the 'kill' command to kill the BASIC task.

The new style panel is being shipped on new 3000/4000 systems at this time. ESD immunity is enhanced by providing better grounding between the controllers and the CCA frame. This is accomplished by adding a mesh to the rear panel cover to provide better contact between the I/O connector bracket of the controllers and the rear panel. Serviceability is improved by providing better access to the controller stack. The new Rear Panel has a removable cover over the I/O connectors of the controller stack. Removing the cover provides a bigger opening for the I/O connector brackets facilitating the installation of the controllers on the stack.

The following is the recommended procedure for installation of the MAI 2000/3000 at a customer site: o Unpackage the CCA cabinet from shipping cartons. o Open CCA cabinet and remove the packing material from inside the cabinet. (Follow instructions inside CCA cabinet) o Make sure that all PCBA's are seated correctly. (DO NOT change the switch settings on any of the controllers) o Close CCA cabinet. o Plug the unit into dedicated line receptacle. o Power-on the system and perform a standard load. o Do an alt.load and run the SIT diagnostics. o Install diagnostics into hard disk. (Optional) If the system does not power up correctly then perform the normal troubleshooting procedures. Verify that all diagnostics run successfully before you continue with your normal installation procedures.

The O/S is functionally compatible with BOSS/IX used on the MAI 2000/3000 systems. 2.0 NEW HARDWARE The MAI 4000 contains the following new hardware: 1. Expansion Unit (EU) cabinet 2. Expansion Interface A (EIA) o Includes two additional parallel printer ports 3. Expansion Interface B (EIB) o Includes six additional peripheral controller slots 4. 4MB Memory Board 3.0 EXPANSION SUBSYSTEM The Expansion Subsystem consists of an Expansion Unit (EU) cabinet, two bus extender cards (EIA and EIB) one in the Base Unit and one in the Expansion Unit, and a set of cables to interconnect the two. The mechanical outline for the Expansion Unit is the same as the Base Unit cabinet (i.e., MAI 3000 cabinet). The EIA resides in the Base Unit on top of the I/O controller stack and logically buffers the EBUS signals prior to extending CPU-BASIC FOUR-2500,3000,4000,4114------------------FIB045 Pg002 them to the EIB in the Expansion Unit. 4.0 4MB MEMORY CARD The functionalities offered by the 4MB memory card are similar to those of the 1MB memory card. Up to six 1MB and 4MB memory cards can be intermixed, provided that the memory capacity does not exceed the maxiumum of 16MB. The 4MB uses the same address as the 1MB, the only difference being that the 4MB has to be addressed before the 1MB cards. 5.0 PARALLEL PRINTER CONTROLLER The parallel printer controller is located on the EIA controller. It allows the attachment of two more parallel printers (in addition to the parallel port on the CMB) for a total of three parallel printers. 6.0 RESTRICTIONS 6.1 EXPANSION UNIT The Expansion Unit will support a maximum of six additional controllers with the following limits: 1. 8-Ways --------------- (Up to 6 Controllers Max.) 2. WDC Controller ------- (Up to 2 Controllers Max.) 6.2 CMB Requires a 3rd Art-Work CMB with Rev. level N or higher, to access more than 8MB of memory and support the Expansion Unit. 6.3 WDC Controller Drive 0 or WDC 0 has to be in the Base Unit. If installed in the Expansion Unit the system will not load. 6.4 LAN, MTS, MCS, AND 4-WAYS Supported in the Base Unit only. 7.0 POWER ISSUES 7.1 POWER LOSS The MAI 4000 system with both a Base and Expansion Unit are to be treated as a single unit, with respect to power loss. In other words, if power to either unit is lost, the system will cycle down. 7.2 POWER ON/STARTUP If the Base Unit is powered on and the Expansion Unit is not correctly cabled or does not have power, the Base Unit can operate as a single box. If power is restored to the Expansion Unit subsequent to system startup, the Expansion Unit and all its component will be ignored. The system will have to be shutdown and re-booted to enable recognition of the powered on Expansion Unit.

[ WPSF 435 ] *** Problem: A terminal(s) appears to be hung or if no other terminals are logged on, the system appears to be hung. You will most likely find this problem when you log off then cannot log back on again. The terminals which are active will continue working until a logoff takes place at which point the terminal will 'hang'. Cause: The process id 1 is suspended on a 3000 or missing on a 2000. There is a small 'window' in the process handling in which this process suspends. Usually, the suspend is a result of a port that is logged-off flooding the system with escapes. To verify: On an active terminal, do a 'ps -a'. Look for PID 1. On a 2000, it will not exist. On a 3000, the status will be SSPD. Workaround: Upgrade to 7.3 or 7.4.

The first entry in the dump error log is a 0:16 or a 0:0 which can be found using the dmplog command. Usually this will occur just after a print job has finished printing and, to date, on systems that (1) have a maximum configuration with more than one printer or (2) are over configured with one printer for the amount of memory in the system. Here are some examples of configurations on systems that have reported this problem: 3000 -- 2MB Memory, 9 users/terminals, 2 printers 2000 -- 1MB Memory, 7 users/terminals, 1 printer Cause: The memory is corrupted. The system goes to 'free memory' which has already been accidentally freed. Also during memory compaction the system detects 2 adjacent free sections because one of the free sections had already been freed. The bus error is caused by 2 processes accidentally sharing the same memory. Workaround: Upgrade to 7.4 Do NOT configure more user/terminals than the system has the memory to support. (This might only cut down the chances of the crash, but the crash could still occur.)

SOLUTION: Jumpers 16 to 17 and 18 to 19 must be installed if the PMMU is present. REASON: Jumper 16 to 17 establishes the state of a Fast Table Search in the PMMU. If this jumper is not installed, one additional clock cycle might be introduced to the total time during a Table Search. Jumper 18 to 19 controls the Early Processing Startup for exception processing in the PMMU. If this jumper is not installed, all PMMU initiated operations are extended by 6 clock cycles. Since the PMMU does not arbitrate for the logical bus in the CMB design, the jumper must be installed to prevent the additional delay in all PMMU access and improve performance.

PROBLEM DETERMINATION: If a 4/8 way port receives a mixture of bad parity followed by a stream of good parity data, in a repetitive manner, memory may get corrupted and cause a wide variety of symptoms. FIX: Carefully observe the ERRORLOG for any ports logging errors, also quiz all operators for any unusual display problems that may have occurred prior to the system crash/hang. This problem can be caused by defective terminals, phone line/modem/mux problems, defective/unterminated data cables, turning terminals off/on repetitively, etc. Eliminate all possible causes of serial port data errors. It is also a good idea to have all serial devices left powered on all the time the system is operational. The problem was identified on a 4000 system at 7.4B, but could conceivably occur on any SPx system. It is hoped that this problem will be corrected in a future O.S. release. This problem appears to be worse on a heavily loaded system, and may not require many repititions of the bad/good data to cause a failure. Also the system may crash (or hang) several minutes after the data stream has stopped (could be a varying length of time before the corrupted area of memory is accessesd).

However, the 2nd and 3rd parallel ports will always be the LAST two configur- able ports. EXAMPLE: If you have a 4000 with 3 8-ways, then you will have 29 ports (0 thru 28). Of course, port 2 is a parallel port and ports 27 and 28 are also parallel. If you add an 8-way, increasing your ports to 37, then ports 35 and 36 become the parallel ports. You will not have to change the configuration of ports 27 and 28 because it will move with the port assignment. You will never be able to configure the last 2 ports as terminals because they are reserved as parallel ports. The physical position never changes because these ports are located on the EIA board in the main chassis of the system. ORIGINATOR: D.

Mechanical Interference. This problem may occur when using CMBs P/N 903631-003/MM532520 and P/N 903631-004/MM532550 to replace a defective system board. Late production CMBs have a wider connector plate that interferes with the rear panel. The extra width prevents the CMB from seating properly on the CMB standoffs. ECN 13886 has been released to correct this problem in future production boards. To get around this problem in the field, loosen/remove the CCA rear panel before aligning the CMB to the standoffs. After the CMB screws are tighten, reinstall the rear panel, do not tighten the screw on the lower right corner if the interference is greater than 1/8 inch. 2. Location of nylon washers. The four plastic washers used to mount the CMB to CCA standoffs should be installed between the CMB and the head of the screw to prevent edge shorts. o Install washers in screws at locations: 1F, 1H, 1L, and 1P/R. Systems manufactured before 4/4/88 were assembled incorrectly with the washers between the CMB and the standoffs. Remove the washers and reinstall them as indicated above.

Thus an approximately 1/2" section of sheet metal on the corner of the supply must be removed to allow proper insertion of the supply on the CMB. This section can be cut or folded back diagonally. Supplies (MM532525) for the 2500 already have this ECN (12939) done.

The system could not read the superblock. Reformating the drive using.FAVI did not change the symptom, even though it formatted fine. FIX: These drives can also be used on the MPX systems. We got two drives that were formatted for MPX (1024 bytes per sector), using the capacity command in FAVI will show this. The DSC diag will also fail the superblock test. If the standard format is used in FAVI it will read how it was formatted and re-do the drive using 1024/sec. It must be formatted using the non-standard option, changing.the bytes per sector to 200 (hex) and blocks per track to 36 (hex). NOTE: Some older models of the 380MB drive must be formatted using 35 hex blocks per track. Use 36 hex and try to format. If this fails then try 35 hex.

To set the system time to 00:00:00 you would use the statement 0100 SETTIME0. It changes the value of the TIM system variable to 00:00:00. Two accounts (one SPX and one MPX) were experiencing problems with their system times reverting to 00:00:00. Hardware did not fix the problem. A global search was done on the applications programs for the SETTIME command but none were found. However when a global search was done on the entire system a match was found in a GAMES program, the Word Unscramble Game. It used to come standard on BBIII systems. Both of these accounts had previously upgraded from BBIII systems and kept their GAMES programs on the system. Apparently some employees had found out about the GAMES programs on the system and every time they used Word Unscramble it would cause the system time to revert to 00:00:00. This caused serious problems with applications programs that needed the correct system time. Statement 2010 in program .GAMES.%3!12 was the culprit. You can change the statement to a REM statement but the best solution is to just delete the program.

TROUBLE DESCRIPTION: The drive is formatted in the MPx format of 1024 bytes per sector. Using FAVI, formatting using the STANDARD format will not correct the problem because the format parameters are stored on the SCSI drive. FIX: Using FAVI, select NON-STANDARD format and change parameters to match SPx system. The parameters (mode sense information) must be set as follows: Formatting Parameters (all data is hexadecimal) --------------------- Tracks per zone : 8 Alt. Sectors per zone : 5 Alt. tracks per zone : 0 Alt. tracks per volume : 10 Sectors per track : 36 (If formated for MPx this will be 1C) Bytes per sector : 200 (If formated for MPx this will be 400) Interleave factor : 1 Track skew factor : 0 Cylinder skew factor : 8 Sectoring flag : 40 Sense data length : 1F Medium type : 00 Write protect : [ disabled ] Disk Drive Geometry ------------------- Cylinders : 660 Heads : 8 Precomp cyl : 0 Read/write current : 0 Step rate : 0 Landing zone : 0 As with a standard format you still may not interrupt the format process or the drive will not function and need to be sent back to maxtor to be re-thumb printed for MAI Basic Four. Once this procedure has been completed, a standard format may be selected. Because FAVI uses the parameters from the previous format when a standard format is selected, this procedure should only need to be performed once to correct the table of format parameters. This should only affect add on disks to existing systems and not new systems. NOTE: Some older models of the 380MB drive must be formatted using 35 hex blocks per track. Use 36 hex and try to format.

Verify the CMB PROM size jumpers on the -005 CMB, jumper 46 must be connected to 47. If this is not correct, the amber light on the CMB turns on and there is no message displayed on the screen. 3. The drive must have an id of 5. Jumpers JP12, JP13 and JP14 on the bottom of the drive assign the id. JP12 and JP14 should be jumpered and JP13 should be left open. 4. If upgrading to 7.5B from another OS level, a configuration record is necessary. PROBLEM: Error -89 when trying to install the operating system from tape.

This FIB does NOT apply to differential SCSI busses such as the external SCSI bus used on the external tape drives connected to the GPx systems. The SCSI (Small Computer System Interface) bus must be terminated at both ends of the bus. The SCSI controller has built in termination, however the other end of the bus MUST BE TERMINATED at the last device and ONLY THE LAST DEVICE on the bus. Terminator packs must be removed from any other SCSI devices on the bus. NOTE: The dual SCSI Disk Controller used in the SPx systems has two independent SCSI buses with a single disk attached to each bus, in this case both disk drives MUST be terminated since the buses are independendent and each is on a seperate cable. The terminators used are either SIP (Single Inline Packs) or DIP (Dual Inline Packs) which contain 220/330 ohm networks with the 220 ohm resistor tied to +5V and the 330 ohm resistor tied to ground and where each signal on the bus is connected into an individual network. +5V | 2 2 0 signal ------* +3V inactive state 3 3 0 | ----- --- - The signals are negative (ground) active and when properly terminated each inactive signal should be approximately +3V. To check for proper termination, disconnect the SCSI bus cable, power up all SCSI devices and measure the voltage at each SCSI device between pin 1 (ground) and pin 2 (Data bit 0). The signal voltage on terminating devices should measure approximately +3V and the voltage at non-terminating devices should measure approximately ground. Measurements at a device with the terminator packs reversed will read approximately +2V. Measurements can be made with a DVM or an oscilloscope. It may be easier to connect the SCSI bus cable to the device being checked and measure the voltage on an open bus connector, however you must be sure only one SCSI device is connected to the cable at a time.
