64MB Limit on 8570 / 8580 Configuration The 8580 SC.EXE only supports 64MB. If you have somehow stuffed in two MC-64 cards, the system will barf. 8580 Video- The VGA supports a maximum of 720-by-400 picture elements (PELs) in the text mode and 640-by-480 PELs in the graphics mode. The VGA can support 256 colors or 64 shades of gray at one time. Composite video is not supported. Note that the 8580 provides Base Video, so it only provides one or two AVE slots. Warning: Some non-IBM graphics adapters drive rather than receive VGA signals. If more than one adapter that drives a VGA signal is installed in a system, both adapters will be damaged. Comments on ALPS and Mitsubishi Floppy Drives >There was some dust on the fdd controller below the fan, but I've seen pcb's in even worse condition. This machine seems to be on duty not for long time. I also cleaned the drive (mitsubishi type), but all didn't help. Peter said >Ask somebody for the drive from an unused 8580. > How long is the half life time of these drives? They seem to die quite often! The ALPS drives had a much higher error rate than the Mitsu-drives.
The ALPS are also much more wicked to take apart due to the amount of "0"-sized
Philips screws. The Mitsu is a somewhat cheap design, but far more easier
to service. Both drives are dust collectors due to the lack of a dust-shield
covering the disk slot when no floppy is in the drive. Replacing
Capacitors >For replacment of the 22uF and 1uF caps, I used surface-mountable electrolytic caps of the same type. However, 0.22uF electrolytic caps are difficult to obtain, so I used ceramic caps instead. I also used ceramics there, and tantalum chips for the others. Just a note that I occasionally repeat: the best way
of locating bad electrolytics is by checking ESR, effective series resistance.
A dandy little meter for this is a kit made by Dick Smith Electronics in
Australia, and sold by various dealers around the world. Floppy Support Structure

The contacts on the battery point to the rear, where they press

The Day Time Stood Still (Time does not Change) j131 asked I am using this machine under linux (debian 2.2.r3) as a sort of occasional (in fact rather rarely turned on) home-file-server. The only symtom is that: _the time at powerup is the same as it was at powerdown_. Neither BIOS nor OS complains... Only me... There are no 161/163 errors. Alfred Arnold replies
with "just the facts" Record number: H024809 INTERMITTENT CONFIGURATION ERRORS (161, 162, AND 163) MAY BE CAUSED BY LOW BATTERY VOLTAGE OR A DEFECTIVE SPEAKER BATTERY ASSEMBLEY, FRU P/N33F5950.

Clear a Power-On Password 
With the assembly shorted, power-on the computer. This erases
the power-on password. Remove the short after POST is finished. Clear CMOS by Shorting Modules to Ground Record number: H104756 8580 systems use CMOS to store system configuration. CMOS may become contaminated for various reasons. The current field procedure is to remove the battery and allow CMOS to drain until the configuration is no longer present, which may take several hours. A faster way to drain CMOS is to short the CMOS modules to ground. ">> DISCONNECT THE BATTERY FROM THE 8580 SYSTEM <<" Locate the CMOS modules, identified below and by using a meter lead connected to frame ground, such as the power supply case, carefully drag the meter lead around each of the respective modules, contacting each of the pins. This will immediately drain CMOS. Connect the battery. CMOS modules are located in the following positions for the following systems: 8580-041,071 (16MHZ) in position U186 & U187 8580-081,111,121,161,311,321 (20MHZ) in position U146 & U186 8580-A16,A21,A31 (25MHZ) in position U132 & U152 (Near Blue Conn.) If problems are still encountered after draining CMOS, normal problem determination should be performed to determine the cause of defect. Open a 8580 
Use a coin or large standard screwdriver to turn the
two large screwheads to the left. After they are both loose (they're captive
screws, they won't come out), pivot the side cover on the bottom hinges until
the top edge has cleared the case. Pull up and out. If the lock in the top center of the cover is locked,
look at the next section. Remove
Front Bezel NOTE This bezel is NOT like the 95 bezel where there are upper pivots.
There is a single catch to the right of the power switch. Think of the two
bottom catches and the top catch in the same way you'd pick up a bowling
ball (which I haven't done since High School). These "fingers" grip the frame
of the case and pull the bezel onto it. Open a Locked 8580 (and 8560/8565) Tony Ingenoso sez: It's very easy if there's no card in the bottom slot, less easy if there is. 1) Flip the machine upside down ALTERNATIVE APPROACH: -- drill
a couple of small holes in the bottom of the case where the cover tabs are
located, then use these holes to apply pressure to the tabs to get them to
release. This doesn't involve having to waste something in slot 8, but it
does involve mangling the case to a very minor degree. Use a depth gauge!!!
If you drill through the retaining tab, there'll be nothing to push on ;->
>16MB on a 8580 under Linux Ed Avis takes time out from the pub and mistakenly admits: I upgraded my 8580 from 12MB to 24MB RAM and Linux's ibmmca.c SCSI driver stopped working. (I have a couple of Spock Primes in there.) To cut a long story short, this is caused by a DMA limitation on the 8580 (and possibly other early PS/2s) that restricts DMA to the lower 16Mbyte of RAM. Michael Lang, the maintainer of the driver, was very helpful and after trying various bugfixes, suggested changing the flag 'unchecked_isa_dma' to 1. I'm not sure what this does, but it fixed the problem. So if you have >16Mbyte RAM and you find that Linux crashes on boot with errors from IBM MCA SCSI, edit the file ibmmca.h in the kernel sources and change a couple of lines to read: unchecked_isa_dma: 1, /*32-Bit Busmaster */ \ instead of 'unchecked_isa_dma: 0'. Hopefully this will become
an option in later versions of the kernel - or maybe with the new 2.4 kernel
and 4.0 ibmmca driver it is not needed. 161/163 Trivia Peter "remembered" this- If the floppy *seems to start* booting (LED lights up, FDD whirrs for a second) after the beeps and 161 / 163 display but then "hangs there" press [F1] to force loading. The older Mod. 80 seem to have a *slighly* different BIOS that not always auto-loads even a valid reference disk. After 161/163 errors the first loading of the reference disk *may* take up to 90 seconds - because the machine BIOS uses the lowest transfer rate available, because it is uncertain about the type of FDD. If the F1 fails and a second F1 brings you into IBM ROM BASIC suspect
Memory Errors Note: Power-off the system before removing or replacing parts. 00011000 indicates a system-board parity-check error. If two system-board memory-expansion kits are installed, remove the kit in the connector labeled either J15 or J8. If the problem disappears, replace the kit. If the problem remains, replace the kit in the connector labeled either J16 or J9. If that does not solve the problem, replace the system board. 00011100 indicates a memory-adapter parity-check error. Remove the memory adapters from the expansion slots, one at a time, until the error goes away. Remove the memory-expansion kits from the last adapter removed. Install the memory-expansion kits, one at a time until the error returns. Replace the last memory-expansion kit installed. If that does not solve the problem, replace the adapter. 00021500 indicates a failing system-board memory-expansion kit in the connector labeled either J15 or J8. Replace the kit. If that does not solve the problem, replace the system board. 00021600 or 00022100 indicates a failing system-board memory-expansion kit in the connector labeled either J16 or J9. Replace the kit. If that does not solve the problem, replace the system board. Memory Activation / Deactivation The Model 80 activates and deactivates memory in 1MB blocks, except for the first 1MB of system-board memory. For this block, the following occurs: If the POST detects an error in the first 512KB of system-board memory, the first 1MB block of system-board memory is deactivated and the following occurs: - If an additional 1MB block of system-board memory is installed, the addresses assigned to the deactivated block are reassigned to the second block of system-board memory. This is only true for the first two 1MB blocks of system-board memory. After the first two blocks, an error code is displayed. - If additional system-board memory is not installed, no address reassignment occurs and an error code is displayed. - The first 1MB of memory address space cannot be assigned to adapter memory. After the first 1MB of memory has been tested, it is assigned addresses. If the POST detects a memory error in any memory after the first 1MB, the 1MB block of memory is not deactivated and an error code is displayed. In this event, the customer-level diagnostics program can be run to deactivate the 1MB block and reassign the addresses. This program is on the Reference Diskette supplied with the system. After the addresses are reassigned, the defective block is ignored by POST during subsequent power-ons. 
If errors occur one at a time, the system deactivates 1MB blocks of memory. However, if two errors occur at the same time on the same 80386 Memory Expansion Kit, the programs on the Reference Diskette cannot be loaded and an error message is displayed. If you don't try to run the Mod. 80 with more than 16MB RAM (which is a story of its own) and if the busmaster is designed within the limits given by IBM (which is the case for the SCSI's and the XGA's) you won't get into many troubles anyway. *But* there have been busmastering cards known as troublesome - because they tried something "off standard" - like the Buslogic BT-64x cards, which were explicitely named in the original ECA text along with other cards. The ECA's had been listed in the earlier versions of the EPRM - but for the last ones they had been thrown out. I'll try to dig out an older EPRM version and see if I can get the original text. Ah - I guess I found one: ECA008 is the "speaker noise" ECA (valid for 8580-111 S/N below 6019000 and -311 S/N below 6502022) with Planar FRU 90X7390 *and* a 387 FPU installed. ECA011 is the 386/387 conflict ECA, valid for -111 / -311 with board FRU 33F8415 with EC-level a79694 and / or REA number 18600149 and lower (instead of the EC number). ECA031 is the "busmaster ECA" but a different text that I recall. This refers also on the "initial system board" FRU 90X7390, which has an EC level below EC C00835 *in either case* and the reference is made for the "Wizard" adapter but the IBM SCSI adapters are also mentioned. So there is a general problem with the busmastering on these early level boards at all. I think they won't work properly at all. The most common failure mentioned is a 110 Parity Error with a busmaster. ECA035 is "8514/A in 8580" but this references downlevel 8514 cards rather than the Mod. 80 at all. ECA040 is the "314MB drive not coming ready" ECA - valid for -311s equipped with a second 314MB ESDI drive - caused by a failure in the HDD logic board. ECA048 is the second "busmaster ECA", which mentiones both 90X7390 *and* 33F8415 boards as potentially affected. They list some cards: Known troublesome are Bicc Isolan, ComTech Channel/2 and /2+, IBM Wizard / Portmaster / XGA (!!), Metacomp Psconnect, Northern Telecom LanStar/MC, Proteon P1840 Pronet-4, Racore 4x16 Network card, Yarc Micro785+. The Lan Technologies Microprint Network is listed as "under review", but that is *still* not the full ECA I have in mind. Maybe it is one of the earlier drafts of the final ECA. ECA051 is an "OS/2 trap / NMI" but for 25MHz boards. ECA069 is "162 + 601 POST error" ECA - caused by downlevel FDDs on all early PS/2 (50, 60, 70, 80). That's what I found so far. Very friendly greetings from Peter in Germany Record number: H021673 The two Base Frame Assemblies used for the 8580 are NOT INTERCHANGEABLE. The Base Frame Assemblies contain the thumb screws to attach adapter cards. FRU P/N64F0157 is used for Models 8580-041, -071, -081, -111, -121, -161, -311, -321. FRU P/N64F0157 contains a metal back plane required for EMC purposes and should not be removed. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ FRU P/N64F0158 is used for Models 8580-A16, -A21, -A31. FRU P/N64F0158 DOES NOT contain a back plane assembly because there are components on the back of the system board. 1780 POST ERROR ON 8560 & 8580 Record number: H064300 WHEN A 1780 POST ERROR IS DISPLAYED ON AN 8560-041 OR 8580-041, VERIFY THAT THE FIXED DISK CABLES ARE INSTALLED PROPERLY. CORRECT INSTALLATION OF THE CABLES IS SHOWN IN THE MODEL 60 AND MODEL 80 HMR. Intermittent parity error 110 on an 8580 during POST, diagnostics, and applications Record number: H006554 PROBLEM ISOLATION AIDS: When advanced diagnostics fail to detest a bad system board memory card, the cards in J15 and J16 should be swapped and diagnostics re-run.. Advanced diagnostics loads into the first 256K of memory and will test all memory above 256k with multiple bit patterns that stress test the memory cards.Stress testing the first 256K is not possible because the test would write over the diagnostic program. You can test all the memory by swapping the two memory cards and re-running the memory test. 8580 Does Not Support SCSI-2 F/W (Corvette) Record number: H125078 Compatibility: The IBM SCSI-2 Fast/Wide SCSI Adapter/A is supported in the 8590/95 & 9576/77/85/90/95. BIOS on earlier 32bit systems (8570 & 8580) do not support this Adapter. |
