UltraStor is not out of business. Call 714-581-4100 and ask them yourself.

Last month I returned one of the first 14F's for repair/upgrade. My card
was replaced with and upgrade. And the damn thing failed just exactly the
same way as the prior one did. Then I noticed new jumper definitions in the
new manual (quite sure they were not in the original manual, which I can't
find at the moment) where one can set the maximum time the card occupies
the ISA bus. Default was 11uS. Set to 9uS it works. At 11uS I couldn't get 
thru DOS 5.0's fdisk without a lockup. Golly! Isn't it great how COMPATIBLE
the Industry Standard Architecture bus is?
