TWGS DMA and RamFast SCSI--HELP!!

[sagochangi@aol.com (Sagochangi)]

I read a while ago (from Supertimer) that the TWGS is fully DMA compatible with
the RAMFast SCSI controller.  And that certainly isn't the first time I've
heard that.  But my experience has been different.  I bought a TWGS a while
ago, anxious to use all the new speed.  But the card absolutely refuses to boot
with my RamFast in the system, even with the RamFast set to TWGS: YES, and DMA
off.

Nathan Mates' old accelerator FAQ lists the -2B GAL as being a necessary DMA
fix, and the RamFast manual itself (p.40) says of the -2B GAL, "The
RamFAST/SCSI will not function in your computer until you get this replacement
part".  And the TWGS works fine without the SCSI card in the system, so I can
only assume that I do need the chip.

Tony Diaz shows a completely compatible RamFast card on his site, rev D (same
as mine), although chip U9 on his card is v3.00, whereas mine is 3.01F.  Could
this make a difference?

Here, also, is the information I've gathered on my TWGS: version 8H, rev. 1.4x.
 Performs at 6.3 mHz in Transwarp mode.  Card is installed in slot 3 on a ROM
03.

The error code reported at boot time is as follows:
   RamFast-SCSI fatal memory fault code=0C
Sometimes, instead of getting an error message, my system simply crashes into
the Monitor.

Can anyone tell me if there is a work-around for this problem?  If not, please,
*please* (he wrote with his own blood), can some kind soul tell me where I can
get the -2B chip?  I can't give up my hard drives, but I can't keep going at
2.6 mHz, either.  Replies by email are appreciated.

Thanks,
