Hello,

According to the output, the roms appear to be loaded without error. Also, note that the floppy boot signature check is enabled, so make sure the last two bytes are correct (verify with a hex editor if possible):

Code: Select all

00000000000i[HD   ] Floppy boot signature check is enabled
00000000000i[MEM0 ] rom at 0xfffe0000/131072 ('/usr/share/bochs/BIOS-bochs-latest')
00000000000i[MEM0 ] rom at 0xc0000/41472 ('/usr/share/bochs/VGABIOS-lgpl-latest')
Are you running bochs or bochsdbg? What happens if you run bochsdbg with the same configuration? (You will need to hit "c" (Continue) in the console window.) Given the last bit of output, I suspect you are just running the debugger and not telling it to Continue.
