Also, sometimes it appears that *after* a flash is done, one may have to
first load its defaults BEFORE trying to reconfigure it for your system.

The "extended" CMOS RAM (byte 65 and above) contains various chipset
register settings, eg memory timings, FSB settings, peripheral
configuration info, etc. Any RAM location can have any function as
defined by the BIOS code. For example, there is no guarantee that BIOS
version 2 will store the SDRAM memory timings at the same CMOS RAM
location as BIOS version 1, so one could expect a black screen during
the first POST after a BIOS flash. Clearing the CMOS RAM and reverting
to defaults circumvents this potential problem.

Thanks for that info, Frank. I think I should take a look into it a bit
more.

And I also need to figure out how to get back to Ultra DMA Mode 5, since
that option wasn't available in this current BIOS. (Ultra DMA Mode 4 was as
high as it goes, or at least as it shows up in its config list). I'm not
sure if that means I'm stuck in Ultra Mode 4, or just that the BIOS doesn't
know any better, since I *do* know I was able to get it in the other BIOS
(i.e., the HD's support it). But this is the only BIOS version I can use,
for this specific microprocessor upgrade.
