Hi, This AMD Elan board seems to be very problematic: http://www.embeddedarm.com/products/board-detail.php?product=TS-5500 I'm having various issues with booting recent Linux kernels with syslinux. syslinux-2.13 was the last version that worked and since syslinux-3.00 it doesn't work. When it doesn't work all I get is "Boot failed" from the bootsector. Since the obvious change since 3.* is the eddcheck and commenting that piece out does make 3.* work (3.02 and 3.70). It can be similated in bochs using the bios which is available here: ftp://ftp.embeddedarm.com/ts-x86-sbc/old-downloads/binaries/5500BIOS.ZIP How should I proceed? Thanks Sean

Unfortunately, preliminary analysis seem to imply that it is not just the BIOS, but the actual CPU which is causing some of these problems. The EDD check is a different issue entirely, which might be possible to emulate. -hpa

Do you mean: - It doesn't work at all until the patch, then it is problematic? - It is problematic until the patch, then everything works great? To me, the above can be interpreted both ways. -A

The BIOS you pointed me to unambiguously claims EDD is supported, it clearly also has code to use EDD, and yet it fails when one attempts to use it. Have you attempted to contact the vendor about this problem? -hpa
