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.
