I still got a 486 DX4-100 and maybe an even older machine, as well as a couple of voodoo cards and old gfx cards (ISA and even VL-BUS).

It would be interesting seeing early to mid 1990's PC emulation, CPU level - AMD, WinChip, Cyrix and the like.

I have a heap of old early 90's parts, including a strange very long graphics card with something that looks like PCI on one end of a standard ISA connector. Another (ISA) graphics card has a removable BIOS with 1987 on the sticker, but it doesn't always work right and text mode artefacts appear once Win98 runs.

it would be nice to have all this stuff dumped, of course

but before to have them emulated, i'd prefer to have a little bit more of object-orientation in MESS, i.e. not to need a hundred of different systems for any possible keyboard+card+cpu combo... wink

I gathered it was better to bump a related topic rather than create a new one:

I just ripped the BIOS from my Gigabyte GA-586HX board - this one is dated 03/19/1997. The current "at586" MESS BIOS is dated 01/22/1996.

It's not really worth running in the preliminary MESS driver since it probably needs a completely new "clone" driver for other chips; it crashes on load with "intel82439tx_pci_write(): Unexpected PCI write 0x90 <-- 0x00000002".

Yeah, I would assume from the model name that your board has the HX chipset, and MESS's at586 emulates the TX one so that won't go as-is smile

heihachi_73: Have you submitted that rom to the mess team yet? Eventually someone will probably add HX support, if we had the rom for it...

I didn't think anyone would want it, with all of the BIOS images out there, how would I go about doing that?

I have three BIOS images from 5 old boards (not counting the PCs over the GHz mark). The two boards that don't want me to copy are the IBM 486 (proprietary BIOS) and the Packard Bell (AMIBIOS which doesn't want to flash, setting or different to others?). I can't even find the BIOS on the board of that thing! The Packard Bell program has a BIOS image which is in parts - I can't tell what it is. I prefer a single 384K file dump which can be cut to 128K wink

The 3 dumped BIOSes (all Award ones so far):

Epox P55-IT board - 95/08/04
The above Gigabyte board - 97/03/19
Pentium Pro board (unknown model) - 97/04/15 (not a 586 of course!)

I also have a couple of things (possible bugs or not) to add, if they're not already known (Win32 build):

(both) Insert key (unthrottle/fs11 mode) is enabled even in full keyboard emulation mode.
(OldUI) The File Selector seems to be missing a backslash so files selected come up mounted as "C:\diskimgWin98SE.ima", notice the lack of the \ before the Win98SE part. It creates an unformatted 360K disk image of that filename as well.
(OldUI) Pressing Tab in the File Selector (directory list) locks up MESS.

Err, for Pentium+ boards the image probably *should* be 384k or more - as Aaron and I were discussing earlier most halfway modern PCs bankswitch the BIOS smile

The three above images, dumped by the Award program, were 384K... I "tidied" them up to fit the 128K MESS dump, so you could probably just resize them if need be:

The BIOS images were a triple of the same part - on the Epox (1995) one the image was 3x 128K parts all the same. The Gigabyte and i686 ones had the first 256K full of just 0xFF.

On another story I have just dumped another BIOS - a 512K Phoenix BIOS from the HP 1.2GHz Celeron machine. I highly doubt this "Pentium III based" thing would end up in MESS in the next few years; I'd hate to see the speed!

I have the BIOS upgrade program for the Packard Bell PB680 machine but it seems to only be a flash upgrade; I want to dump the ver.11 without installing the ver.12 update! Doing it the hard way would be too tedious for just another BIOS - it's a 40 pin surface mounted Intel chip!

Can you send me the 'untidied' and 'tidied' dumps? I'll send them where they need to go.
I'll PM you my email, if you can't find it.
