Re: Using an HSZ50

[Bill MacAllister <post+alpha-linux@macallister.grass-valley.ca.us>]

Michael,

Thanks for the pointer.

The reason that there are errors reading the partition table is because 
there is none at this point.  fdisk does cannot read the device.  How did 
you create a partition table on your hsz70?

I have a couple of other questions is you don't mind.  The HSZ50 is 
differential scsi.  I got a qlogic controller that supports differential 
scsi mostly because I was not sure if I could use my Adaptec 3940uw with 
it.  (I don't need to boot off of the HSZ so it does not need to be visible 
from SRM.)  Is differential scsi electrically different enough that you 
can't mix differential and non-differential?

Finally, there is a scsi/tulip como card in the system that I have ignored 
up to this point except to use the ethernet interface.  Can you tell me 
anything about this card?  Should I try plugging the HSZ50 into it?

Again, thanks for you help,

Bill
