Alright....I GIVE UP!!!
I'm trying to write a device driver for an A/D card on a 
COMPAQ 386/20e running ESIX 5.3.2 Rev C.  

Question:
Does anybody know how to use the DMA support routines mentioned
in the ESIX/386 release notes?  I have been able to DMA small chunks
of data; I also have: (a) locked up the system, (b) caused a PANIC
trap, (c) gotten several core dumps; (d) combinations of all three.

Any suggestions would be appreciated.....e-mail please.

Note - several calls to ESIX tech support have gotten me nowhere except
talking to the phone-answer person!
