Hi

IMHO inserting the code at the beginning of the BIOS routines is a bit risky.
You never know, if there are parts of the Bios, which do not like being speeded up or cached (We've seen M$ and Borland getting probs with faster CPUs).
I would put it at the very end, just before booting.
This place could be a bit harder to find. Some Bioses are stored compressed and get decompressed by a tiny loader module at start and executet from memory.

You may think about this as well:
Why not putting it into any adapter rom?
ISA-Nics are pretty cheap and do usually provide a socket for a Bootrom.
IIRC The Adapter scan is done rather late, so most of the Bios has already been executet. An adapter Bios contains a few special Bytes at start, a checksum (IIRC) and then your code. There should be a description to be found on the net somewhere.
Best: If you have any problems, just remove the nic and you are back to normal.

Hi

There is an old tool, called amisetup (IIRC latest Ver is 2.99).
Runs frm DOS only.
You may use this to check, if any of your two Bioses got hidden options, matching your needs.
But I guess, that's not what you want to do, because it's too easy :wink:

Hi

No, you cannot unlock those features, but IIRC you can alter the settings for those hidden features in the CMOS, just as if those features were unlocked.
