You use these programs, and their results entirely at your own risk. Background: ~~~~~~~~~~~ The VIA EPIA motherboard, with recent BIOS versions, has the ability to display a fullscreen boot logo when booting, instead of the usual POST screen. The logo itself is embedded in the BIOS image, and although its 'filename' has the extension .BMP, it is *not* a BMP file - it's an odd but simplistic format referred to herein as AWBM. The boot logos created by this program have only been tested so far with my VIA EPIA motherboard. They may work with other boards with similar BIOS capabilities, they may not. What does it do? ~~~~~~~~~~~~~~~~ AWBM2TIFF and TIFF2AWBM convert images between 8-bit (256-colour) TIFF and the custom AWBM format used by the EPIA BIOS. This second release has better support for greyscale images, and no longer chokes if an alpha channel is encountered. What doesn't it do? ~~~~~~~~~~~~~~~~~~~ These programs *CANNOT* modify a BIOS image, or extract logos from a BIOS image. For that you need a program like CBROM (version 2.xx recommended, Windows only, unfortunately). These programs are only intended for use with full-screen logos - they *CANNOT* be used to create EPA (Enery Star) logos. How do I customise my Boot Logo? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ First create your logo in a graphics package. For the EPIA you need to make a ***0x480 image with 256 colours. Once you've done that, save it as a TIFF file, and use: TIFF2AWBM logo.tiff logo.bmp to convert to AWBM format. (The original logo in the EPIA BIOS has the filename ***D.BMP, though it's most definitely *not* a BMP file...) Now use CBROM to insert this logo into the BIOS image, by typing: CBROM EPIA0205.BIN /logo logo.bmp If this succeeds, you can now flash your machine with the modified BIOS image. Note - if your logo is very elaborate, CBROM may complain that there isn't enough room in the BIOS file. The EPIA0205.BIN BIOS has about 18k of free space for the logo - but a ***0x480x256 image takes about 300k uncompressed. The BIOS image is a basically a catalogue of lha files, so you can use lha to guage how much space your logo will take when it's compressed: lha a test.lha logo.bmp *HINT* If you're having trouble keeping your logos small enough, try to avoid dithering, and make sure any gradients are vertical (i.e. horizontal scanlines have constant colour); this will help maximise the compression that can be achieved. *UPDATE* If you're desparate for more BIOS space for your logo, it may be possible to remove certain parts of the BIOS to make room. On the EPIA 5000/800 BIOS version 0207, you can safely remove the pxe.lom network boot rom, and the EPA logo, with: CBROM EPIA0207.BIN /pci release CBROM EPIA0207.BIN /epa release Obviously, doing this results in a machine that can no longer boot over a network, but the free space for the boot logo is increased to around 45k. If you still need network boot functionality, it may also be possible to replace the pxe.lom boot rom with via-rhine etherboot rom, which supposedly works, but is considerably smaller. Please note, though, that I haven't tried this... *WARNING* While I am currently using a pxe-less BIOS on my EPIA-5000, and it's working nicely, it's quite possible that attempting the same thing on other machines / BIOS revisions will result in a system that won't boot. You proceed at your own risk!
