- AMI BIOS Considerations
- Revised July 17, 1992
-
- [Note that Washburn and Associates sells new AMI keyboard BIOS chips
- for $15 plus $4 shipping.]
-
- There's been a lot of misinformation on the network AND from IBM
- reqarding AMI BIOS compatibility with OS2.
-
- The misinformation from the net comes in the form of well-intentioned
- OS2 users that have OS2-compatible AMI BIOS, informing the world that
- all is OK with AMI. The fact is, most user's who have AMI bios will
- not experience problems - but there are a few well-defined cases
- where older vesions of AMI BIOS are known to cause incompatibilities.
-
- The misinformation from IBM comes in the form of inferences in their
- TIPs & TECHNIQUES help file that all AMI BIOS earlier than a certain
- date or revision are suspect. That simply isn't the case - as many
- successful OS2/AMI user's will testify. In addition, IBM technical
- support people do not seem to have the following information (at
- least in this writer's experience) - which would go a long way in
- acknowledging that there is a problem in certain cases.
-
- Both of the aforementioned cases are unfortunate in that they have
- been frustrating user's with real AMI BIOS problems, stalling or
- preventing proper corrective action - and ultimately leaving a very
- nasty taste for OS/2 and compounding OS/2 reputation problems. It
- is the hope of this writer that this information will allow those
- last bastion's of frustrated OS2/AMI user's to get on-board and
- start enjoying the power of their newly acquired operating system.
-
- The following information is a copy of a fax provided by Clyde
- Washburn of Washburn & Co. Washburn & Co. has been working with IBM/
- Microsoft on AMI BIOS compatibility issues since version 1.1 of OS2.
- The fax directly addresses AMI BIOS compatibility guidelines.
-
- According to Mr. Washburn, this information is known by IBM (Boca
- Raton), and also resides on CompuServe.
-
- Here is the fax in its entirety:
-
- Washburn & Co.
- Distributors of AMI Motherboard and BIOS Products
- 3800 Monroe Avenue, Pittsford, NY 14534
- 716-248-3627 FAX 716-381-7549
-
- CONSIDERATIONS IN THE USE OF THE AMI BIOS WITH OS/2:
-
- <Updated 7/8/92>
-
- AMI BIOS's of modern vintage provide a Screen ID code, visible at the
- lower left of the screen during the initial RAM count, and which can
- be made to return by resetting with Ctrl-Alt-Del, or frozen on-screen
- by holding down the <Ins> key at boot to create a Keyboard Error, which
- will stop the screen for the error message:
-
- AMI BIOS and AMI BIOS Plus: aaaa-bbbb-mmddyy-Kc
-
- AMI Hi-Flex BIOS: ee-ffff-bbbbbb-gggggggg-mmddyy-hhhhhhhh-c
-
- If the screen ID code is in a form other than this the BIOS is either
- extremely old, or was produced by a company with a source code license.
- In the former case, contact us for update information, but in the latter
- case ONLY the motherboard manufacturer will be able to provide further
- information or updates. ALL Everex 386 BIOS's are in this latter
- category.
-
- GENERAL RULES:
-
- 1. If an IDE type hard drive is installed, the date ("mmddyy") should
- be 040990 or later for use with ANY operating system, DOS included,
- due to the special timing requirements of IDE drives which were
- accommodated on the date noted.
-
- 2. With any other drive type, such as MFM, RLL, ESDI, or SCSI, OS/2
- may be expected to install and operate correctly if "mmddyy" is
- 092588 or later, provided that the Keyboard Controller Revision
- Level is suitable for the version os OS/2 being used. Note also
- that in the case of SCSI hard drives, a driver compatible with
- the version of OS/2 being installed may be provided by the con-
- troller manufacturer, and if so, a special installation procedure
- may apply.
-
- 3. The Keyboard Controller Revision Levels ("c" in the Screen ID Code
- Examples above) expected to produce proper installation and opera-
- tion are as follows:
-
- OS/2 1.0 or 1.1: 8, B, D, or F
- OS/2 1.2x: D or F
- OS/2 1.3x or 2.0: F
-
- 4. If the Keyboard Controller Revision Level shows as 0 or M then the
- Keyboard Controller chip is NOT an AMI chip, even if an AMI License
- sticker was applied to it by the motherboard OEM. This means that
- its performance under OS/2 is unknown - it may or may not work cor-
- rectly. In some cases (usually "M") an AMI chip can successfully
- replace a non-AMI chip, but this is NOT a general rule - sometimes
- the non-standard Keyboard Controller (usually "0") was used to com-
- bine motherboard functions not normally part of the Controller,
- and substituting a standard chip will cause the board to not func-
- tion at all. In this case there is no solution other than replace-
- ment of the board. A Revision Level of 9 accompanied by a non-
- standard ID Code also indicates a non-standard controller (and BIOS),
- and the motherboard manufacturer should be contacted for further
- information.
-
-
- BIOS UPDATES:
-
- If a BIOS prior to the dates noted above requires replacement, note the
- following:
-
- 1. AMI BIOS and BIOS Plus series BIOS (16 character ID Code) for CACHED
- motherboards are customized for individual motherboard designs, and
- can ONLY be obtained from the motherboard OEM, with only THREE
- common exceptions:
-
- a) BIOS's with "aaaa" = E307 can often be replaced with a standard type.
-
- b) BIOS's for Northgate or Motherboard Factory motherboards EXCEPT
- the Northgate Slimline can be replaced by a standard type. Slimline
- BIOS's have the VGA BIOS in the same chips, and can be updated to
- the 040990 release provided that they are identified as being
- Slimline, and the speed is specified (20, 25, or 33 MHz), since
- different VGA code is required for the various speeds.
-
- c) BIOS's with "aaaa" = DAMI, DAMX, or EDAMI are usually for cached
- boards designed and/or built by AMI, and if so can be updated.
- Mylex or Leading Technology boards with these prefixes can ONLY
- be updated by the board manufacturer.
-
- 2. The complete Screen ID Code is required to properly address whether
- a BIOS update for other motherboards can be provided, and in the
- case of the Hi-Flex BIOS the complete SECOND and THIRD lines of
- the ID Code are also necessary. If not immediately visible on
- the screen they may be viewed by pressing the <Ins> key during
- boot-up.
-
- END OF FAX
-
-
- P.S: Well there it is folks. I hope this file will assist in alleviating
- any nagging questions as to whether it's the BIOS or a system
- setup problem confounding you OS2/AMI users.
-
- By the way, the fax doesn't mention the symptoms of a bad BIOS
- version - which I suspect are different depending the the
- specific motherboard design (chip set) and the particular BIOS
- version. But for the benefit of those who have the same con-
- figuration as my machine, perhaps this will save some diagnostic
- time:
-
- Motherboard: Aramus 386 33/25 Mhz - Intel discreet logic.
- Keyboard: Enhanced (101). Dip switches set to 101
- mode. (NOTE: OS2 or DOS does not work with
- any other setting.)
-
- AMI ROM BIOS: SINT-1185-040990-KD
- AMI Keyboard BIOS revision -KD (should be -KF for OS2 2.0)
- OS2 2.0 Problems: (not an exhaustive list)
-
- 1. CAPLOCK and NUMLOCK cause loss of keyboard control.
-
- 2. Entering a WINOS2 Session causes loss of keyboard control.
- Setting KBD_RATE_LOCK to ON prevents this problem.
-
- 3. Selecting Special Needs under the keyboard setup icon
- intermittantly stalls the system.
-
- I'd suggest that if other users find that a replacement BIOS solves
- a particular problem under OS2, that the net be made aware of the
- version replaced and the symptoms/problems the new BIOS solved so
- that such diagnostic info. can be added to the OS2 FAQ.
-
- Would the keeper of the OS2 FAQ please take note and
- update the FAQ accordingly. I don't want to have to
- continually re-post this.
