I don't think so -- I temporarily removed that message, and made sure that the initial code (what used to be in doc_stage1.S) matched the previous version that worked. It didn't make any difference - it still locked up on the P-133's, but not on the Athlon. For what it's worth, on one of the PC's, the lockup occurs at line 363, in the readbyte loop. We copy a few pages OK (%di = 0x400, 0x500, 0x600), but lock up when %di is between 0x700 and 0x800, specifically with ES:DI equal to 0x07E0:0x0719. The other board makes it to the "Jumping to Grub" message, but then immediately reboots. Mark
