I have read all the HOWTO's, FAQs, and archive questions I can find on
this, but still haven't been successful in getting RH5.0 (kernel 2.0.31)
to communicate
with my Adaptec AHA-1520B SCSI adapter.
On install it can't find it with autoprobe. If I give it options
0x340,11,7 or 340,11,7 or 0x340,11,7,1 or 340,11,7,1 it apparently finds
it because it says it's scanning the SCSI bus, but then it hangs the
system and I have to do CNTRL-ALT-DEL to get out and start over. So I
installed RH5.0 without the SCSI adapter, and then tried to
add it as a module. I get
SCSI: 0 hosts
SCSI: detected total
when the system is booting. I tried modifying mkinitrd by changing
| sed "s/.*$module *//"`
to
|sed "s/.*$module //"`
then running mkinitrd, lilo, and rebooting as suggested in one list
archive. Now if I do
insmod aha152x.o
it says
aha152x.o: init_module: Device or resource busy
I tried disabling the SCSI host adapter BIOS, ISA Plug and Play support,
Plug
and Play SCAM Support, Support Removable Disks under BIOS as Fixed
Disks, and Extended BIOS Translation for DOS Drives > 1 GB, but that had
no apparent effect. All I want to do is download some data from two
Exabyte 8mm tape drives connected to this SCSI adapter.
I also tried removing the tape drives but the system still hangs on
install. I tried
using the "max_scsi_luns= " option with different numbers (0,1,8) but
still no change.
My system is an IBM PS/Value Point 486/DX2 66 MHz, with the original 503
MB hard drive (master) and a Maxtor 8.2 GB (slave). All that is
connected to the SCSI adapter are the two 8mm Exabyte tape drives (8505
and 8700LT). I have DOS/Windows95 on the 503 MB hdd, RH 5.0 Linux on
the first four
partitions (~2GB) of the 8.2GB hdd and DOS/Windows95 on the rest. I can
communicate with the tape drives using Windows so I know everything is
in working order, but I need Unix/Linux to analyze these tapes.
I also have a 3c509 network card - I read in the SCSI-HOWTO where
network cards can sometimes interfere but it didn't give any details or
suggestions.
Does anyone have any suggestions?
Thanks,
Carol
