can anyone please tell me the name of an editable vga bios by editable I mean you can edit it in xbtool or something I have tried frosty’s but it is set to check for a DVD drive and I’m planning to ditch the DVD drive. Thanks

Depends on where you intend to install said bios. iND 5001 VGA (256k) and X2 5035 VGA (512k) are both the best VGA bioses out there and both support removal of DVD drive. Also, neither bios need external software such as xbtool to edit. I prefer the X2 5035 but because of it's size, it won't fit on some modchips and so in this case, you would have to go with the iND bios.

so how do you modify them

You edit the text config file for each BIOS. When it boots the BIOS reads the config file from your Xbox disk. The big advantage is that you can make changes without reflashing.
