OK I went and looked, and the reason it doesn't work is that it's loading the award rom into place, and it tries to decompress to shadow, which doesn't work because it's IN shadow. http://bethie.net/~programmer/loadsegs.zip has a few files in it which should help..
loadef.com will put the 128K ef.img file (which should be the uncompressed 'REAL' bios) into the proper place in memory and make it ready to be jumped to.
loadD.com will put a 64K d.img file (be careful here because there are normally 4 separate 16K roms here) into the memory at D0000, should be useful for testing your OEM roms
loadC.com is basically the same thing as loadD.com, but puts the data into C0000
reboot.com, does a warm boot by jumping to FFFF0
the source is included, and if you need to load something to a different address it should be fairly easy to do, or let me know and I'll do it.. the C0000 - FFFFF address range is the only range that can be put into a protective shadow. I haven't spent any time to look where Award decompresses the boot image to..
