Hi all, I am glad to tell you that usbrom can boot grub from usb disk correctly. It can not boot linux by error " Selected cylinder exceeds maximum supported by bios". I suppose that becase of the kernel are located in the second partition of the disk. I will try to make a new usb linux. And try to boot that later.
BTW, Kevin , do you know the reason why the bios does not support larger cylinder?

That's odd. How big is the drive, and what CHS settings are you returning?
Also, I vaguely recall grub having an option to enable LBA based disk reads.

hi kevin, Since the CHS/LBA also has been resovled yesterday, now the problems is that grub can not load the kenerl by "invalid or unsupported executable format". i tried to cat (hd0,0)/menu.lst. It seems the output is not correct too.

Sounds like the CHS conversion is not correct.
Please provide the number of blocks on the disk, and the CHS settings that you are returning.

usb blocks :3907583 CHS = 243/255/63
