 
 What is GBU? 

 ---- 

 It is no secret that many people have had less than wonderful 
 experiences getting OS/2 to work with sub-standard computer 
 hardware.  This document is an attempt to minimize these problems in 
 the future.  It can be used as a shopping list, or to compare against 
 your machine to find if other people using the same hardware have 
 had similar problems. 

 As is the case with any document of this type, it can only be helpful 
 if it is supported by the potential users.  This means that enough 
 people must send in enough messages that a representative sample of 
 the available hardware gets listed.  Please email me new submissions.  
 New versions will be posted as additions are made to the list. 

 Feel free to upload this document to any ftp site, BBS, or online 
 service that does not already have it, or that has an older version of 
 it.

 Usenet Announcement 

 ---- 

 Since many of the problems people have had with OS/2 stem from 
 semi-compatible PC hardware, I will maintain a live document of 
 computer hardware with respect to its performance with OS/2.  I will 
 make this document available by uploading it to BBSs and 
 ftp-os2.cdrom.com.  It will be distributed both as a viewable INF file 
 and as clear text. 

 The working name of the file is "The Good, The Bad, and The Ugly". 
 "GBU" for short. 

 Please send me messages about any hardware experiences you want 
 to share.  In particular I am looking for information on motherboards, 
 video cards, multi-I/O cards, SCSI controllers, floppy drives, hard 
 drives, CD-ROM drives, printers, modems, mice, track balls, graphics 
 tablets, multi-serial port cards, and any other hardware you have had 
 good, bad, or ugly experiences with. 

 The definitions I am using are: 

 GOOD 
    hardware that caused no known problems, software drivers were 
    available in shrink wrap either with OS/2 or with the hardware, or 
    drivers were freely available on BBSs. 

 BAD 
    hardware that has proved to be incompatible with OS/2 due to 
    excessive numbers of trap messages, or OS/2 drivers do not exist.  
    The hardware might still work in DOS or Windows sessions with 
    appropriate drivers. 

 UGLY 
    hardware that has had problems which could be corrected only after 
    some serious work (changing jumpers doesn't qualify as serious), the 
    available drivers take advantage of only some of the features of the 
    hardware, only beta level (or worse) drivers exist, or the hardware 
    works only in a "compatibility mode".  If there are several messages 
    with conflicting votes for a piece of hardware, it will automatically 
    be placed in this category. 
 
 The specific information I need includes:  type of hardware (mother 
 board, video card, etc.), the manufacturer, model number, chip set, 
 serial number range (if it matters), and a vote on Good, Bad, or Ugly, 
 with a specific problem report or glowing recommendation, and any 
 caveats regarding the GBU vote. 

 I may change the GBU designation based on the comments or caveats if 
 they point to a different designation using the guidelines above. 

 If you wish to refute a previous category for a piece of hardware, 
 please provide adequate documentation that the hardware should 
 change from one category to another.  It is almost impossible to 
 promote something from Bad to Good directly without said hardware 
 spending at least one release of GBU in Ugly.  Likewise for the opposite 
 (less likely) demotion. 

 Please send messages directly to me via Internet or the networked IBM 
 BBS based in Canada.  On the (Canada) IBM BBS, send messages to 
 John Altstadt.  Private messages may be sent via the Ibm.Bbsmsg 
 forum or uploaded as files with a note to the sysop to forward the file 
 to me.  On Internet, send messages to altstadt@mprgate.mpr.ca. 

 To reduce the time required to generate a new edition of GBU, I prefer 
 that messages are sent to me in IPF format, as I can just cut & paste 
 them into the source files, and then bang out a new version quickly.  If 
 this is a problem for you, then send them in ASCII format and I will do 
 the appropriate conversion.  These panels show example text that you 
 would be replacing highlighted this way. 

 Not all fields will make sense for all hardware categories. 

 The examples given are for hardware that does not exist.

 Caveats

    16 bit stereo with SCSI-2 port 

 Manufacturer 
    Creative Labs 

 Model Number 
    Sound Blaster 16 SCSI-2 

 Chip Set 
    Creative CT174x 

 Comments 
    Drivers supplied on MMPM diskettes.  The card comes with DOS and 
    Windows drivers and software.  New drivers for DOS, Windows, and 
    OS/2 are available via anonymous ftp from Creative Labs at 
    creative.creaf.com.  The DOS drivers will let you change the IRQ 
    and DMA channels, so the card can be set for IRQ10 under OS/2 and 
    Windows, while older DOS programs can use IRQ 2, 5, and 7 inside a 
    BAT file wrapper.  OS/2 will allow DOS programs to change the IRQ 
    on the fly.  See the Good SCSI Controller cards section for more 
    info. 

 Caveats 
    The SB16 cards are known for hiss, clicks, and pops when playing 
    8-bit wav files.  Some of the system sounds skip the first chunk of 
    the file, but sound correct when using the Audio Player.  The 
    updated drivers from Creative Labs solve these problems.  OS/2 will 
    allow DOS programs to change the card IRQ on the fly, which has 
    potential for serious problems.

 Comments 
    Good and cheap 

    Double Speed successor of the LU-Drive; driver kit available on 
    various BBSes (mitfx.zip; 17131 bytes).  Includes MMPM/2-Support 
    (CD-Player).  Easy to install.  Can use upper interrupts (10,11) or 
    software polling. 

 Caveats 
    I had to change the audio connector from 1234 to 2143 to connect to 
    to my soundblaster clone.  This may not be a problem mit other 
    Soundcards 

    No OS/2 drivers shipped with the drive, To install OS/2 from CD-ROM 
    you need to change the first boot disk (explained in the 
    mitfx.zip-archive).

    From what I can tell the drive is a Sony OEM.  However, no drivers 
    for OS/2 can be found nor do the current Sony drivers work with 
    the card.  However, the DOS drivers provided do load in a DOS box

 Comments 
    Machine operates with AMD 486DX40 CPU run at 50MHZ, jumper 
    selectable CPU speed, otherwise very stable 

 Caveats 
    System hangs and occasionally reboots when Mediavision PAS-16 
    uses 16-bit DMA channels, sometimes displays errors about not 
    finding basic ROMS during 16-bit DMA induced reboot, PAS-16 
    sometimes works flawlessly if there is no hang on system boot-up.  
    Not tested with more than 16MB of ram.

 Model Number 
    EISA-VL-Bus (Part #09-173-05 Rev A) 

 Chip Set 
    Intel / Pheonix BIOS 

 Comments 
    Very unstable from day one.  Manufacturer support was poor (they 
    refused to call me back, said it was OS/2 and not their board, would 
    not provide RMA for return of Board for them to test; even after I 
    offered to pay for the testing and shipping to and from, etc).  
    Continous Trap 000D, 000E, and 0002 when I was able to even get it 
    to load.  Used built-in controllers, even worse.  Used 3 different 
    video boards, 2 different HDD/FDD boards, 8 differnt HDD, 4 different 
    FDD, 3 different CPUs, 8 different SIMMs (56Meg, same manufacturer, 
    one of their reccomeded ones and Part #), etc.  The only thing I 
    didn't change was the MB itself (even changed the cache).  Spent 4 
    months on this board, over 225 reloads before giving up (PC mag 
    gave this board a #1 reccomendation).  Fair Docs 

    P.S.  ALL of the hardware used works fine on another MB and my 
    current MB!  Some of the problems I am sure are also attributable to 
    the BIOS and not the MB. 

 Caveats 
    When, for the short time periods, it was running it ran like a champ 
    (Better than the AIR I currently use). Fast, clean, crisp.  REALLY 
    wish this board worked.

    Driver is not included with OS/2 nor is one available for this model.

    configurable too!!!  If all cards were this easy you wouldn't GBU!!! 

 Caveats 
    Installing OS/2 from a SCSI-based CD-ROM with this controller may 
    require adding the drivers to the OS/2 boot disk and deleting one or 
    two unneeded drivers.

    Reliable and fast.  OS/2 drivers come with card, but may be old; 
    newer drivers available from the usual sources.  Does NOT include a 
    floppy port. 

 Caveats 
    Older cards have an outdated EPROM that causes OS/2 to crash 
    sporadically.  This ROM has a sticker with a number ending in -005, 
    and should be replaced with a -006 EPROM.  UltraStor will ship a 
    new EPROM free of charge if needed.  If installing OS/2 from a 
    SCSI-based CD-ROM, will need to modify the OS/2 installation disks 
    to include the UltraStor driver.

 Comments 
    OS/2 drivers included in the card's box (available on ftp.cdrom.com, 
    too).  Installation went smoothly, but drivers not as feature-laden as 
    S3 drivers.  Fast card (similar to Orchid S3-805 cards in this respect).

 Model Number 
    Graphics Ultra, ISA Bus, 1MB VRAM 

 Chip Set 
    ATI mach8 

 Comments 
    Although the drivers for mach32 and mach64 are pretty good, the 
    one for mach8 is not worth the hassle to install it.  It simply screws 
    up the DOS sessions.

 Manufacturer

 Model Number 
    Ultra DS600 

 Chip Set 
    S3 801 

 Comments 
    This board is a duplicate of the STB Powergraph board, and 
    evidently the architecture of these boards uses an external clock 
    that OS/2 cannot support.  1) no seamless windows, 2) cannot start 
    DOS windows (but can windowize a FS DOS session), and 3) no 
    background processing to FS windows.
