- SCSI SUPPORT UNDER OS/2 2.0
- ---------------------------
-
- SCSI Hard drive driver support:
-
- SCSI Adapter Driver
-
- Adaptec AIC 6260 AHA152X.ADD
- Adaptec AHA 1510 AHA152X.ADD
- Adaptec AHA 1520/1522 AHA152X.ADD
- Adaptec AHA 1540/1542 AHA154X.ADD
- Adaptec AHA 1640/ AHA164X.ADD
- Adaptec AHA 1740/1742/1744
- (Standard mode operation) AHA154X.ADD
- (Enhanced mode operation) AHA174X.ADD
- Future Domain TMC 850/860/875/885 FD8XX.ADD
- Future Domain TMC 1660/1670/1680 FD16-700.ADD
- Future Domain TMC 600/700 FD16-700.ADD
- Future Domain TMC 850IBM FD850IBM.ADD
-
- Note: These drivers can be found on diskette #8 in a file
- called DASDDRVS. The above drivers can be unpacked with
- the following command:
- UNPACK A: DASDDRVS OS2 /N:xxxxxxxx.ADD
-
- Add the following statement in the CONFIG.SYS:
- BASEDEV=xxxxxxxx.ADD
-
- Once these steps are taken, reboot the machine to initiate
- the appropriate support.
-
-
- -------------------------
-
- Following are a number of notes about usage, and
- about potential compatibility problems with the
- microcode levels on various adapters and devices.
-
- Adapter: All Adaptec adapters
- Note: SCSI hard disks must be configured as SCSI target
- ID 0 or 1 to be able to start up from that hard
- disk.
-
- Drive: IBM 0661 - 320MB SCSI
- Note: Adapter BIOS will not recognize the drive as
- Target 0 or 1 (Drives 80, 81). For OS/2 2.0, the
- drive can be used as a non-startup drive.
-
- Adapter: Adaptec AHA-174x
- Drive: IBM WDS-3180 - 80MB SCSI, IBM WDS-3160
- - 160MB SCSI
- Note: Adapter will not recognize these drives when
- configured in 'STANDARD MODE' (AHA-154x
- emulation). Instead, the AHA-174x adapter should
- be configured in 'ENHANCED MODE'. This mode is
- supported by the OS/2 2.0 drivers, and the
- problem does not occur when the adapter is
- operating in enhanced mode.
-
- Adapter: Future Domain TMC-850/860/875/885 w/BIOS revision
- level 7.0.
- Future Domain TMC-1660/1670/1680 w/BIOS revision
- level 2.0.
- System: IBM Models 35 and 40 when the Future Domain
- adapter is controlling the startup diskette.
- Note: Will produce the message, "Disk read error has
- occurred" when you attempt to start the
- Installation diskette.
- Contact Future Domain for a free BIOS upgrade.
-
- AMI SCSI Adapters
-
- Symptom:
- AMI "Fast Disk" and AMI "Fast Disk II" SCSI
- adapters are incorrectly recognized as Adaptec
- adapters.
- Problem:
- At the final restart after the installation is
- complete, delete from the CONFIG.SYS file, any
- line with "BASEDEV=AHA1xxx.ADD" (where "x" can
- be any character). Ensure the line,
- "BASEDEV=IBMINT13.I13," appears in the CONFIG.SYS
- file.
-
-
- Problems with Always IN2000 SCSI adapter
-
- Internal Processing Error.
- Symptoms of the problem are varied, but the most
- common is an FDISK error on the second diskette.
- Problem:
- Bios adapter with bad bios. Bios level of 3.06A
- or 3.20 should be upgraded. The current BIOS level
- is VCN:1-02 and works with OS/2 v2.0.
- Resolution:
- Upgrade to current BIOS level of VCN:1-02. Also,
- Always IN 2000 SCSI Host Adapters may require an
- EPROM upgrade from Always for $20 to operate with
- V2.0. The revision level should be 2.5-2.7.
- Always suggests installing the EPROMS and
- re-formatting the drive - seem to be some problems
- installing over DOS partitions. Always can be
- reached at 818-597-9595.
-
- Bernoulli Boxes
-
- Notes:
- 44 and 89MB drives will work if connected to any
- other SCSI card other than Bernoulli's own card.
- The drive will work as a large diskette and will be
- non-bootable.
-
- PROCOMM+ SCSI MCA adapters do not work
-
- Resolution:
- Contact PROCOMM for details on OS/2 support.
-
- Slow SCSI support or missing icons
-
- Symptom:
- Slow hard drive speeds and possibly no icons
- appearing. Other data corruption possible.
- Problem:
- Hard drive and adapter card settings not
- correctly matched.
- Resolution:
- Ensure that hard drive and card are matched in
- their settings of SYNCH and ASYNCH mode.
-
- IBM 16-bit SCSI cards(early versions)
-
- Early versions of the IBM 16-bit SCSI adapters
- may experience problems and report erroneously that
- the device is not functioning.
- Resolution:
- Replace SCSI card with a card with updated microcode.
-
- Quantam Plus Hardcard
-
- Symptom:
- Numerous failures under 1.3 and 2.0.
- Problem:
- Microcode lower than 2.6 will cause numerous
- failures under 2.0. Also, drive cannot be second
- disk if installation will take place on the hard
- card drive.
- Resolution:
- Call Quantum about EPROM upgrades.
-
- Other SCSI hints
- ----------------
- Some SCSI card have jumper pins which can be set to either
- Synchronous or Asynchronous mode. There have been noted
- problems such as no icons appearing or slow hard disk
- performance. This can be attributed to the SCSI card and
- hard disk not being set to the same asynch or synch
- settings. Either way, they must match. Be sure these are set
- properly.
-
- The early versions of the IBM 16-bit SCSI adapters may
- experience problems and report erroneously that the device
- is not functioning. This can be corrected by replacing the
- SCSI card with a card with updated microcode.
