- HELP ! (Please)
-
- Several people are running 2+ SCSI devices with an adaptec 1542B, why
- can't I ? :-(
-
- I'm trying to get an IBM 3510 <Toshiba XM-3101BME> CD-ROM drive to co-exist
- with a MAXTOR 7120 SCSI HD, and I'm having __NO__ luck.
-
- I have been using the CD-ROM drive since October (data and playing Audio
- CDs), and when I needed more Disk space, I decided to add a SCSI drive
- instead of another IDE drive. I can get either of the devices to work,
- but not both at the same time. The device with the SCSI ID closest to
- 0 wins.
-
- ALL SCSI DEVICES ARE SCSI 1.
-
- System: 25 MHz AMD 386SX, Opti chipset, AMI BIOS, 10 Mb RAM.
- Maxtor 7120A IDE C: drive.
-
- The card has default jumper settings, except: floppy disabled, 5.0 Mb/sec
- transfer rate.
-
- I am running the files from OS2CDROM.ZIP, and the 12-07-92 aha154x.add
- from Adaptec's BBS.
-
-
- BASEDEV=AHA154X.ADD /V /A:0 /!DM:1,2
- with the HD at 0, and CD-ROM at 2 or 1, I only get a D:,E:,F:,G: DASD HD
- (that works 100%), and OS2CDROM.DMD doesn't install (SYS1201).
-
-
- BASEDEV=AHA154X.ADD /V /A:0 /!DM:2
- with the HD at 3, and CD-ROM at 2, I get no DASD HD, but I get a D:
- CD-ROM (that works 100%) and according to the drives icons, I have an
- F: drive!
-
- my playcd.exe program (IBM program that came with the 3510, for OS/2 1.2+)
- recognizes drive F: as a valid CD-ROM drive, but one that is never ready
- (as it is a MAXTOR 7120S fixed disk drive with DOS 3.3 size partitions).
-
- NOTE:
- with the HD at 3, and CD-ROM at 2, DOS 3.3 and ASPI4DOS.SYS / ASPIDISK.SYS
- will recognize the HD, and it works great !
-
-
- BASEDEV=AHA154X.ADD /V /A:0 /DM:3 /!DM:0,1,2,4,5,6
- gets rid of the extra F: drive icon, but still no HD.
-
-
- I borrowed another 1542B from a friend, swapped it with my board,
- and got the same results.
-
- I also borrowed his Toshiba XM-3201B CD-ROM drive, again no luck.
-
- With the following setup:
-
- Maxtor 7120S HD ID 0
- Toshiba XM-3201B ID 2
- Toshiba XM-3101BME ID 4
-
- Verified with: BIOS (debug, g=dc00:6), booting DOS and loading
- ASPI4DOS.SYS /D, and with SCSICNTL.EXE written
- by Roy Neese of Adaptec (unsupported SW, Roy
- is said to have written it on his own time).
-
- Only the HD is accessable.
-
- Shutting down, unplugging the HD power cord, and rebooting makes only
- the CD-ROM at ID 2 accessable.
-
- Shutting down, unplugging the CD (ID2) power cord, and rebooting makes only
- the CD-ROM at ID 4 accessable.
-
- Several cables and terminators have been tried.

- both of these were tried:

- 12-07-92 5:01p 16662 0 aha154x.add
-
-
- OS/2:
-
- I got rid of a
- SYS2068: 1 messages lost
- os/2 error (while config.sys was loading the 921207 aha154x.add with
- the /V switch) by changing from the default 5.7 to 5.0 Xfer rates!
- Strange ?
-
- DOS:
-
- My system works at 8.0 MB/sec (set with jumpers) using BIOS and DOS,
- but hangs when loading ASPI4DOS.SYS.
-
- It works at 6.7 Mbytes/sec with ASPI4DOS.SYS /D /X01 which should
- override the card's jumpers (when set to 5.0 Mb/sec).
-
-
-
- QUESTIONS: Most SCSI users have more Motherboard horsepower than I
- do. Could I be experiencing phasing problems ?
-
- When using 2 1542B's in a system, how should the second
- board be configured (for aha154x.add) ?
-
- (a second 1542B is cheaper than a new 32 bit Motherboard and 2 4Mb SIMMS,
- or another CD drive, AND I still have my friend's card :-) )
-
- This all seems very puzzling to me, and if anyone has any suggestions,
- I'm all ears.
-
- Any help or suggestions will be GREATLY appreciated !
-
- Thanks in advance,
