I compiled a loader binary with BTXLDR_VERBOSE defined. I have no experience with ASm programming, and know very little about PC booting process internals, so I don't know if I'll be able to do much better about this. I'll anyway keep looking. For now I'm sending the output from the verbose loader when trying to boot with a USB umass device just in case someone can understand something from this: -------- Attempting Boot From USB Device _ BTX loader 1.00 Starting in protected mode (base mem=9f800) Arguments passed (esp=9e78c): Relocated bootinfo (size=48) to 9f7b8 Relocated arguments (size=18) to 9f7a0 BTX version is 1.02 Relocated kernel (size=690) to 9000 Client base address is a000 Client format is ELF text segment: offset=1000 vaddr=0 filesz=2f8bc memsz=2f8bc data segment: offset=31000 vaddr=30000 filesz=5568 memsz=c7e0 Loading complete --------- This is the screen just after locking up. The cursor at this point goes in the second line(where the _ is) and keeps blinking there. (the first line is oviously from the BIOS, but I included it for completeness) Thanks in advance for any help! -- Guido Falsi
