MyLogo won't accept GIF or compressed BMP. Messes up colours in JPG. Ideas?

Hey all!

Trying to put a new boot logo for the wifes PC. It's using a P4C800 Deluxe
mainboard.

Asus includes a program called "MyLogo" to import a new image into the BIOS,
but it doesn't seem to like any GIF I choose. It won't accept a compressed
BMP. JPG seems to be accepted, but it messes up the colour palette pretty
badly. What I'm left with is uncompressed BMP files, which are pretty big
(300K+) and won't fit into the BIOS.

Does anyone know any reasons for this or any tricks to get it to work?

This post and some similar ones, recommend 640x480 by 16 colors. This
will cut the file size in half (instead of a byte per pixel, you end
up with a nibble per pixel). This has something to do with the default
screen resolution/palette during POST.

The software says 256 colour (8 bit) color images... This is actually
"MyLogo2". The default BIOS logo definately contains more that 16 colours.

Thanks!

I tried to pull the OEMLOGO file out of the BIOS, using AMIBCP75, the
BIOS "editor", and the file doesn seem to be 8 bit color, but for
me at least, the file is truncated, so the original logo doesn't display
properly. And yet, it doesn't look compressed either, it is just a
short file.

This is a short explanation about mylogo versus mylogo2. Apparently,
mylogo2 support 8 bit color, so you are right.

When you tried GIF, was you GIF type 87 or 89? I would try the original
format for GIFs, on the off chance mylogo2 doesn't have a full GIF
parser.

I'm surprised the program isn't trying to compress the image somehow.
Since you have succeeded in getting _something_ to work with the
program, maybe you should get a copy of AMIBCP75 and extract the
resulting logo from the BIOS file, so you can reverse engineer the
thing.

AMIBCP75 can be found on the crazyape site (direct links to
BIOS tools are frowned upon, sorry). Using altavista.com and
that site as a search time, it is the third link down. Once on
the site, go to "downloads", then scroll to the bottom. The AMIBCP
program is a DOS program that takes over the screen, so don't be
shocked when your monitor goes to 640x480 mode after you double
click on it :-) Since Asus AMI BIOS files are stripped or something,
you cannot do much with that program except have a look around, or
extract a file.

When you extract the logo you've managed to store, it would be
interesting to see if it is always stored as a BMP or is just a
direct copy of the file you fed to mylogo2. If it is a recognizable
format, maybe you could change your original image to that format
to begin with.

If you get tempted to manually install the logo using AMIBCP75, I
don't recommend that, unless you can find evidence that someone
has succeeded doing that already. The CBROM program couldn't work
properly with the Asus Award BIOS (at least it didn't for me, and
I tried several versions), so what are the odds that Asus's idea
of an AMI BIOS is standard enough to work with AMIBCP ?

HTH,
Paul
