SUBJECT: How to configure a Removable Media Device under DOS
Minimum BIOS Requirements:
Local BIOS 1.21L or later for Series 15, 44 and 441
Local BIOS 1.00L or later for Series 70.
EISA Configuration options(Series 15,44,441 and Series 70 EISA mode)
1. Set "Auto Selection Timeout for Non-Existent Devices" option to [DISABLED]
Required if the cartridge is NOT present at SCSI Controller POST completion,
and therefore the state of the option "Removable Harddisk Caching" WILL be
[DISABLED].
2. Set "Target Allocation for DOS Sequentially from ID 0" option to [ENABLED]
3. Set the SCSI ID of the Removable Media device so that there is a gap
between the SCSI IDs. For example:
SCSI HD @ ID 0 and Removable device @ ID 2 or 3,4,5,6.
ISA Switch Configuration for Series 70 ISA mode)
1. Set SW2-6 "Auto Selection Timeout" to "ON".
Required if the cartridge is NOT present at SCSI Controller POST completion,
and therefore the state of the option "Removable Harddisk Caching" WILL be
[DISABLED].
2. Set SW3-6-"Target Allocation Like Adaptec" to "ON".
3. Set the SCSI ID of the Removable Media device so that there is a gap
between the SCSI IDs. For example:
SCSI HD @ ID 0 and Removable device @ ID 2 or 3,4,5,6.
"Removable Harddisk Caching" Requirements
1. The Block size must be 512 bytes per block; running "UT13.EXE"
version 1.8 or later will confirm.
2. The SCSI must report itself as a Removable Media Device, not Optical
or WORM, and can be confirmed by viewing the "DEVICE" information under
"UT13.EXE" version 1.8 or later.
3. Set the EISA Configuration option "Removable Harddisk Caching" to [ENABLED]"
or
Change Switch SW2-4 on the Series 70 (ISA Mode) to "ON".
ASPIHDD.SYS
The Aspihdd.sys driver that is shipped with the AMI SCSI Controller has limited
support for removable devices. The current Aspihdd limitations are such that
the partition information must be identical in all the cartridges used. This
restriction will be lifted in subsequent releases.
In the interim, if you are using removable devices, we recommend that you use
the drivers which are supplied by the manufacturer of those devices.
