Hi,
i have recompiled the redboot for floppy on an i386 compatible PC platform and works perfectly. I tried to compile for booting from the flash (BIOS). Does anyone did that? If so please let me know the whole procedure and if possible where to find a correspond bin. What i did was the redboot.bin with the booting image passed into the flash. In order to have at the boot sector of the flash to booting image i copy paste the reboot.bin(64k) accross the size of the flash. Please advice.

The ROM startup is configured to boot the I386 from its reset
vector. I only ever tested it on the Bochs simulator, never on real
hardware. At the very least it would probably need some additional
hardware-specific code to complete the hardware initialization.
I don't know what the requirements for booting an application from
flash via the BIOS might be. There is no support for that in the
current sources.
