Hmmm... Bochs seems to find the BIOS and execute it just fine (well until later on, that is) without mucking with anything. Attached are my Config and config files. The payload will eventually be an etherboot image which will boot from IDE (CompactFlash) -- offhand, do I use any old ethernet driver for etherboot, since I'm falling back to IDE? And do I use (for example) ne.img, ne.lzrom, ne.o or ne.rom? None of them are being identified as an ELF image, even though the etherboot config file is saying to create ELF images. Regards, Andrew
