Thank you Mike.

Chipset support for two chipsets is open.
The two chipsets include Acer Labs M 1487, and M6117.

Chipset modules for other parts can either be implemented by the user or licensed from PC Engines for a one-time fee (no royalties).
Further you clarify,

preliminary test code is available
for VIA CLE266 and C3, with a cost of approximately 3k$.
May I inquire whether VIA has any plans to release its chipset information to the public, as apparently Acer Labs has done?

This, in other words, is the "classic" 01ch of bios of yesteryear, right? Elsewhere you explain that tinybios uses 16 bit code, and relies upon "unreal mode"

I am curious to learn, if you can discuss it, your experience or plans with a wholly protected mode bios replacement?? I am not sure exactly what Michael H was referring to, but I do enjoy the sound of that word "DAWN".

Mike Gonta is not associated with tinyBIOS in any manner.
OOPS, sorry Mike, sorry Pascal, in this case, ignorance is not blissful....
"dawn" sounds like a terrific idea.
Will you be working alone, or will "dawn" become an integral part of FASM forum, now that you have converted "tiny bios" source code from A386 compatibility to FASM syntax? Will you have as your goal rewriting bios, but keeping the same functionality, or generating a completely revised version, which does not, for example, support "obsolete" hardware, like, as an illustration, ISA bus? Pascal mentioned in his documentation, which I erroneously attributed to you, sorry again for my error, that he uses preferentially flash memory, rather than hard drive. That could imply setting up USB functionality before implementing IDE or SATA controller interface....Will you adopt a similar perspective? Isn't it surprising that neither Intel nor AMD seem interested in such endeavors??? Reminds me of General Motors attitude about electric automobiles in the 1970's. I am waiting for the TaiWan company with the most to gain, perhaps ACER!, to create a wholly different cpu design which may even interface with an existing socket, to permit development of a completely new software, one based on the fundamental difference between motherboards of today, with gigabytes of memory available, versus the mere kilobytes of precious memory available in the 1970's when the current cpu designs were foisted upon us. In my opinon, "dawn", your new, protected mode bios, which we obviously require, is merely a stop gap measure. What we need, (not taking anything away from "dawn", nor suggesting that a protected mode bios may actually represent "sunset"), to construct a thoroughly revised operating system, exploiting our bountiful memory capacity, is a new cpu architecture.

Sounds like a cool project, I have some code that may help you eg: pmode floppy driver etc. Let me know if you need them ( all written in fasm Wink ).

PS: These doc on bubachs site may help too : http://bos.asmhackers.net/docs/vga_without_bios/
