Having just upgraded my system to Linux SLS 0.99, I now find that the boot
disk created during the install process, containing the Linux 0.99 kernel,
no longer supports my EISA SCSI board in Standard mode by doing 512-byte
transfers (to avoid the bug in the board when doing 1024-byte transfers).

So, to continue getting work done, I need to reconfigure my SCSI board
to run in Enhanced mode (and upgrade my DOS drivers, presumably).

But, the "AHA-174X Family Configuration and Download Utilities" book
and disks refers to a "bootable configuration diskette...normally supplied
by the EISA system vendor", which I don't seem to have (probably it wasn't
delivered when I received the system).

Could someone with an EISA configuration like mine, especially someone
who has succeeded switching their AHA-174x from Standard to Enhanced mode
to support 0.99 (and get better disk performance), please consider
emailing or ftp'ing me a (uuencoded?) image of their "bootable
configuration diskette"?  I have the AHA-174X diskettes with the .CFG
files, but can't seem to get to where I can use those without this
bootable diskette.  I'm primarily using 3.5" disks, but perhaps can boot
off of 5.25" if there's a reason I have to try (advice would be helpful
if you have to supply 5.25").

Of course, Monday or Tuesday I'll call my vendor and see if he's got the
disk(s) floating around there (I'm also missing my BIOS and EISA documentation,
assuming there is such a thing), but for all I know, his shop is closed
for this week, and certainly for this weekend, and I'd rather not be so
dead in the water!

Thanks in advance to anyone who can help me!  My configuration is enclosed
below, in case you want the details.

Of course, if someone has other advice, like how to switch to enhanced mode
using DOS DEBUG or something equally fun, I'd love to hear it!  I have no
software specs for the Adaptec, so I can't make this stuff up myself.  :-)
