Quick question, has anyone put a later version BIOS in this?

Rolling a new BIOS with sane defaults based on normal use would probably be a good idea. It had occured to me but I haven't taken a look yet.

Anyone know the toolchain handy for that offhand? I used to have GUI tools to do the work but don't think I have them archived.

A new BIOS, or any BIOS that actually takes advantage of the SoC features would be great to have. I'm not sure if there's a way to get the battery percentage reliably... And some way to shadow the VBIOS!

Also, what is the very last version of UniVBE that works with this? I am currently on 5.1a, as the latest release requires a 486 to run.

I've been looking for a way to get the original datasheets for the SoC with no missing pages, but it has proven difficult. If anyone can find it or knows someone who has it, please share it - what we have is missing essential pages concerning the AT bus clock timing issues, and some examples on overclocking the bus via software. We could increase the throughput of the video module without compromising the stability of the system if the PIT is accessed too often.
