- Is anyone running 2 SCSI devices with an adaptec 1542B ?
- I'm trying to get an IBM 3510 <Toshiba> CD-ROM drive to co-exist
- with a MAXTOR 7120 SCSI HD, and I'm having NO luck. I can get
- either of the devices to work, but not both. The device with the SCSI
- ID closest to 0 wins.
-
- The card has default jumper settings, except: floppy disabled, and bios
- disabled (I boot from an IDE drive).

-
- with the CD-ROM at 2 or 4, the HD at cd-rom id +1 (ie: 3 or 5),
- and the following in the config.sys:
-
- IFS=C:\OS2\CDFS.IFS /Q
- BASEDEV=AHA154X.ADD
- BASEDEV=OS2DASD.DMD
- BASEDEV=OS2SCSI.DMD
- DEVICE=C:\OS2\CDROM.SYS /N:4
-
- I get the following message at boot up:
-
- IBM CD-ROM Driver
- Version 2.01
- Unsupported Vendor, MAXTOR 7120SCS 3235A219Q5MS
- 1 device installed
- Drive: D:
-
- which tells me that both devices are alive, and if the following config.sys
- line is modified, the unsupprted vendor warning goes away, which means
- the /!SM: switch is working.
-
- BASEDEV=AHA154X.ADD /A:0 /!DM:2,4,6 /DM:1,3,5 /!SM:1,3,5 /SM:2,4,6
-
- I now have a fully functioning CD-ROM drive, and can listen to audio CD's
- with headphones (IBM PLAYCD.EXE for OS/2 1.2 came with the drive),
- but I have no SCSI HD.
-
- with the CD-ROM at 2,4 or 6; and the HD at cd-rom id -1 (ie: 1, 3 or 5)
-
- I get the following message at boot up:
-
- IBM CD-ROM Driver
- Version 2.01
- No SCSI devices found
- SYS1201: Te device driver "C:\OS2\CDROM.SYS" ... was not installed
- press enter to continue
-
- Now I have a SCSI HD, but no CD-ROM drive
-
- Can someone please email me some info telling me how to get both devices to
- work, and I'll post a summary of what I get.
-
- Thanks in advance,
