SCSI-One CDRW Device, 8 LUNs
Gary
on XP. There are several symptoms...
1. During install of XP the install process hung a long time "probing" the
CDRW. For some reason it ended up booting the 2nd time from the CDRW
instead of the CD. (It booted fine for the first boot from the CD.) After
that the install appeared to proceed normally, if slow.
2. Once installed I note that the CDRW appears 8 times on the XP device
manager. Each instance accounts for one LUN possibility. They are all at
Bus 0, ID3 (correct ID), LUN0, 1, 2...7. So XP thinks I have devices at
each LUN at that ID.
3. Also, boot up of XP is torture. During the install it hangs on the CDRW,
probing it exactly 20 times before going on and completing the boot.
The host adapter is an adaptec 2930U2, which both Adaptec and Microsoft
claim has driver support on the XP CD. Indeed, the adapter appears to have
installed without issue (device manager clean for the adapter). Also, the
4416 is on Microsoft's compatible hardware list.
There is a firmware update available for the 4416, but it appears non
specific as to operating system, and old, so I have not done that update
yet. For all I know it's already on there (year 2000 firmware update).
As an added wrinkle, I have an HP photo scanner on the SCSI adapter, too.
There are currently no drivers loaded for this device. It was left attached
by mistake during the installation. The device manager has a yellow ? on
that one. Drivers are available from HP, but I haven't gotten to that small
problem yet :)
All this worked fine under Win98SE. The XP install was a clean install, not
an upgrade of the win98 system.
I have tried different SCSI adapter settings, specifically turning off the
BIOS and the device scan. That had no effect on the XP results nor any
impact on the XP boot delay symptom either. It certainly did reduce the
time spent during early boot, before XP loads, when the scsi devices were
being scanned (reduced to essentially zero).
I'm really stuck here. I've done much research in the archives. Some of
this is similar to other postings (which haven't yet seen a solution), but I
thought that maybe the LUN 0...7 characteristic would trigger something.
Thanks in advance!
