Just a question:  Do you reset with Ctrl-Alt-Delete or with the reset 
swich on the front panel?  Only the latter do the trick with my AHA1542.
Both my Ultrastore EISA SCSI and EISA ESDI controllers do not care which.

This happens when switching from Linux to DOS, right?  Linux has been
using the controller as a true host adapter and set it up with pointers 
into memory etc.  I.e. the Adapter runs natively.  No wonder it does
"Habla ne Espanjola" when DOS thereafter comes and tries to access it.
This problem resides on the host (ISA) side.  If the HW reset does not
work, then that is it, really.  (Unless you manage to get the schematics
from Adaptec, in wich case you may send them to me and I will tell you 
where to solder the swich onto the board... :-)

Well, you may run the onboard BIOS through Debug (e.g: g=C800:5 [Return])
But that will only help you marginally, as the card _will_ do a HW reset
on exit.  You might try it simply to see if it do the trick, though.
