Title: Xbox V1 Chipped, Unsure Of Bios And Want To Go Vga
Post by: Heimdall on May 23, 2010, 12:11:00 PM
You need to know which modchip your friend installed (or at least how big it is) before you can work out which BIOS to use. BiosChecker gives you details of the modchip and the current BIOS - run that and see what it says.

In the meantime, try X2.5035 BFM (512k) and iND-BIOS.5003 (256k) from Frostys_BFM_VGA_BIOS_Pack.rar to test your VGA. Once you have it working and you know what size chip you have, you can flash the non-BFM version to your chip. (This is important - DON'T flash the BFM version because it will brick your Xbox.)

Alternatively, if you want to switch between VGA and standard TV you could just continue to launch the BFM VGA BIOS every time you want to use VGA.

WOOT!

Thanks man.

Used the X2.5035 BFM and it works a treat! Does that mean l can go ahead an flash the non-bfm X2.5035 bios?

I can't get the BIOS checker to boot at the moment. I already had v4 on there, and that couldn't tell me much.

EvoX does tell me however that l have a EvoX M8 FC 06...

Actually got the BIOS Checker to work.

It lists:

CHIP TYPE -> LPC based (SST 49LF020)

512k BIOSES:
1.Bios > Unknown
MD5 Hash = 11B2EB01215A66A98081724A4C0FE93E
2.Bios > Unknown
MD5 Hash = 11B2EB01215A66A98081724A4C0FE93E

256k BIOSES:
1.Bios > Unknown
MD5 Hash = 890C69A33B2D73284DAE8D9F561C3B77
2.Bios > Unknown
MD5 Hash = 890C69A33B2D73284DAE8D9F561C3B77
3.Bios > Unknown
MD5 Hash = 890C69A33B2D73284DAE8D9F561C3B77
4.Bios > Unknown
MD5 Hash = 890C69A33B2D73284DAE8D9F561C3B77

Now off to do some searching on what size the SST 49LF020 is...
