If you have an Award BIOS, and its in FLASH, you may be in luck. Other
BIOSes are a different issue. The process is not without risk however.
There are several editors around. There is a suite of stuff that runs under
DOS (Awdflash, BIOSView, Cbrom and Modbin). It is vital to ensure that you
the right version of the tool for the version of BIOS that you are working
with - don't assume backwards compatibility. Most of these tool run OK with
Windows 9x, but most are flaky at best under Windows NT family.
I have seen (and used) a Windows one called Awdbedit. Its not perfect, but
works well on some BIOSes
Check out
www.biosmods.com and sourceforge.net/projects/awdbedit/.
There is also a tool for building a video BIOS for C&T (Asiliant)
controllers. These are mostly history now, but similar tools may exist for
other controllers.
As an aside, if your Award BIOS will support it (and not all manufacturers
put it in), you can use these tools to put your own splash screen into the
BIOS. This completely circumvents the discussion of slpash screens from XPe.
To minimise risk I would verify that the BIOS that I propose to download
behaves both in CBROM and Awdbedit. As a backstop, I would try to work with
a motherboard that has its BIOS chip in a socket, and get a 2nd chip to work
with (access to an EPROM programmer needed).
