[NTLUG:Discuss] aic7xxx: infinite timed-out, ressetting on Red Hat install

[Kyle_Davenport@compusa.com]

No, don't blame the hard drive.  I have a Quantum Atlas IV u160/m that works
without a problem.  They are supposed to be backwardly compatible.  160Mb/s is
the bandwidth for dual controllers - you would need at least 5 of those hard
drives to saturate it.

I don't see how the AIC7xxx driver is supposed to work if you've disabled the
bios!

Since I posted the initial message, I got some more info on Ultra160
drives. I didn't know this was a SCSI-3 drive. I am not sure what
support there is for this kind of drive. I think the problem might go
away if I just got an Ultra2 drive. I kind of just asked for "a SCSI
drive" from the people at Fry's, and they gave me a very nice one. But I
don't think I will, or even can, make use of 160 Mb/sec with the
hardware I have.

All along, I have just wanted to get this machine up and running on
Linux, bask in the light of the accomplishment, and then after the mail,
database, and web servers are all doing their thing, ...then get a finer
appreciation of all things SCSI. So I may just go back tomorrow and ask
for a more modest drive, and get on with it.
