nice. for a lot of models, they make available a dos/win exe
that produces a bootable floppy image. kind of a pain.
I wonder whether there are any legal or technical reasons to
prevent something like this:
- simple drivers for windows and linux that let you
write the bios code as well as access settings.
- bios update containing a binary blob of code,
with appropriate checksums, etc.
- xml-ish description of the bios settings, something
<setting name="scrub rate">
<description>rate at which a single cacheline of memory
will be verified and written back </description>
<opt val=1> 1ms </opt>
<opt val=2> 10ms </opt>
<opt val=3> 100ms </opt>
<opt val=4> 1000ms </opt>
<location type="byte"> 0x43 </location>
being able to check and interpret bios settings (from the normal OS)
would be a major advantage. being able to set them would be very nice
as well, even if the change didn't take effect until the bios ran again
