The shown procedure is similar to an earlier post on the VCFed.org regarding “EZ-SCSI not detecting card.”
The controller being used is Adaptec AHA-1522, which has both floppy and 50-pin SCSI capability with a built in ROM. The hard drive being used is a Conner CB-3180, which is a 50-pin SCSI that is ~84 MB.
The Adaptec controller has three terminators along with quite a few jumpers on the board for configuration. The following is the current configuration of the Adaptec controller:
Upon boot following POST, the Adaptec AHA-1522 ROM sees the drive and displays the following:
Config.sys has only a device on A drive referring to ASPI2DOS.SYS, which displays the following:
Adapter AIC-6360 BIOS Version 1.20L
Copyright 1989-1993 Adapter, Inc., All Rights Reserved
Target 0: CONNER. CP3180-84mb-3.5 Installed as Drive C:
OS being used is MSDOS 6.22. Following the boot of MSDOS, a line within the config.sys triggers ASPI2DOS.SYS and the following is displayed:
AIC-6260/6360/6370 ASPI Manager for DOS
Version 3.68
Copyright 1990-1997 Adaptec, Inc.
Host Adapter #0 - SCSI ID 0 - LUN 0: CONNER CP3180-84mb-2.5 0D16
The next line in the CONFIG.SYS is for the ASPIDISK.SYS and output is below:
ASPI Disk Driver for DOS
Version 4.01b
Copyright 1989-1997 Adaptec, Inc.
No SCSI logical drives to support.
ASPIDISK.SYS is NOT installed.
When the prompt is displayed, I can type in C: and the system will go to drive C. If I execute, a dir or copy a file to the drive then the response is the files system is not recognized. So, I tried format c: and the response from format is that there is no partition. So, the next step is to use FDISK to set the partition. FDISK immediately freezes the system and requires reboot to clear it out. I tried FDISK several times with the same result. Then I read about AFDISK. And triggered that tool thinking it would partition my SCSI disk.
You have selected a SCSI drive which is controlled by DOS through the Host Adapter BIOS. Use the DOS FDISK and FORMAT commands to partition and format the device.
AFDISK will only allow you to view the drive’s partitions.
So, the next screen shows a block with the statement “Select SCSI drive to partition.”
The only drive shown is labeled as the following:
HA #0 - Target 0 CONNER CP3180-84mb-3.5.
So, highlighting that displays a table with no partitions listed. Another table has the following:
Logical Drive Info:
64 heads
32 sectors/track
80 cylinders
512 bytes/sector
80 megabytes
2837Fh blocks
So, I am at a loss here to understand why FDISK freezes up when I try to partition the drive. I am also at a loss to understand why the tools that were designated by Adaptec to partition the drive will not partition the drive since I am using DOS and I guess the ROM on the adapter.
The controller being used is Adaptec AHA-1522, which has both floppy and 50-pin SCSI capability with a built in ROM. The hard drive being used is a Conner CB-3180, which is a 50-pin SCSI that is ~84 MB.
The Adaptec controller has three terminators along with quite a few jumpers on the board for configuration. The following is the current configuration of the Adaptec controller:
- DMA Channel: 0 (note: apparently, the DMA is not supported in DOS or Windows 3.1 just OS/2; AHA-1522 user’s manual)
- Disconnection: Disabled (note: enabled is default, however, the manual specifies enabled is needed when two or more drives are being used. I have only one. So, I set this to disabled.)
- Following is defaulted on the AHA-1522 card
- IRQ: 11; enable/disable boot from host adapter: enabled; enable/disable fast SCSI is set: disable; enable/disable synchronous negotiation: enabled; Host adapter SCSI ID: 7; and enable/disable parity checking: enabled
- Enable/disable floppy support: enabled (Note: needed by the system, no other floppy support available
- 832 cylinders,
- 6 heads,
- WPC and Landing Zone 512,
- Sectors 33,
- SCSI ID 0.
