RE: [OpenBIOS] New power-up graphics BIOS.

[Jamie Stanley]

Hi there,

Was wondering if I could help! At present (too be honest) not too 
familiar with the OpenBios stuff! But I know its sommit Id like to get into
;)

As for references - I am a software engineer (www.systolix.co.uk) and so
should
be able to contribute in some way ;)

let me know.

cheers - Jamie.

Ralph,

I am using a reference book on the VESA SVGA standard version 1.1 as a
source of code snippets etc:

EGA/VGA: A programmer's reference guide
By Bradley Dyck Kliewer
McGraw Hill Publishers.

I know this is really retro, but if we can stick to code which is a little
way back down the evolutionary tree of hardware, we might be able to create
'instant' graphics from the BIOS.

What would be crucial is some sort of power-up self-testing function, that
determines what kind of SVGA chipset is present, (only the largest families
considered),  and applies different code for each chipset.

Clearly this would be much better hand-coded in C++ rather than assembler;
lest things get icky.

All the best,
    		Gavin.

SVGA may be standard, but which chip-set are you using ?

The system setup can be highly unique for each CPU (PII, PIII, Celeron,
Ultra-Low Power, etc),
"co-processor" (440BX, 440TX, et. al.) and/or Super I/O....
These devices must be initialized before DRAM, PCI bus, etc will get
started, even before the Video driver is loaded.

Interested observer....

Jamie,

Could you or someone else pls. give me a contact telephone no. for Apple
Computers? I desperately need to make a deal with them.

All the best,
