Hmm - I was plagued with problems with my 2920 on a fast (200+ MHz) machine.<br>
|
|||
|
|
I was always having the scsi bus freeze and lock (usually under heavy i/o load),<br>
|
|||
|
|
not only with the penguin-os, but even using<br>
|
|||
|
|
win-dos95 :-) I tried different disks, cables and termination, but I finally gave<br>
|
|||
|
|
up on the card.<br>
|
|||
|
|
Not too sure if I just had a bad card..... or if this is similar to what you are<br>
|
|||
|
|
experiencing.<br>
|
|||
|
|
The 2940 is a much-much better card!<br>
|
|||
|
|
<p>
|
|||
|
|
Lots of luck.<br>
