Troubleshooting IBM- PC DOS / WINDOWS Installation Appendix A
A-6 Software Driver Installation Guide / Owner’s Manual
The
Inquiry ID=0 line
is blank
This means that the device driver located a
interface card which appeared to be a
Future Domain interface card, but was not.
We have seen this with Seagate ST01 and
ST02 interface cards and the CMS SCSI
adapter/ daughter board for the PS/2 Model
30-286 which all use the TI SCSI chip.
2. Versions 1.05 and later of the Pioneer DRD600.SYS driver support
multiple SCSI interface cards. The driver searches for the interface cards
in a particular order, based on the address. This order is CA00, C800, CE00,
DE00. The first adapter found becomes interface card #0, the second #1, and
so on. To tell the driver which adapter to use, the syntax of the /S switch of
DRD600.SYS driver in the Config.Sys must be modified. See #3 below.
3. The format of the statement to be added to the Config.Sys is:
/S:n1[;h1]
where n1 = SCSI ID Number of first Pioneer Changer
h1 = Number of interface card for first drive (default is #0)
4. Example: There is a Seagate ST01 SCSI interface card located at address
C800. The Future Domain interface card has been set to address CE00. The
Changer has a SCSI ID of 4. To access this combination use: /S:4;1
To connect a Changer at SCSI ID 3 to the first interface card and a Changer
with SCSI ID 5 to the second, the setting would be: /S:3;0,5;l Also, set
/N:6,6 to indicate the number of discs available in each unit.
NOTE: Certain versions of the Seagate SCSI interface cards appear twice in
memory. When this happens, the inquiry line will still be blank. If this
happens, raise the interface card number by 1.
5. Some interface cards support dual SCSI devices. This can allow up to 14
SCSI devices to be run off one SCSI interface card. If you are using a interface
card that supports dual SCSI devices, and the Inquiry ID=0 line is missing, make
sure you have selected the proper channel for the interface card. Refer to the
interface card documentation or contact the manufacturer for information about
how to select the proper channel. Try syntax from example #3 above:
1. There could be a conflict with another board installed in the
computer. The Future Domain SCSI interface card is a memory mapped
board and can be mapped into four different addresses (the C000 and
D000 memory segments). See Installation Manual packaged with the
interface card for information on changing jumper addresses.
(There is no Pioneer Changer
model number, or ROM
version number on this line.)
