Bochs just executes boot sector

Post by udarkman »

Im a new user of Bochs and not exeactly understand the use of it.

I install my OS into a floppy disk and then get image of whole floppy with winimage(also tried with partcopy).

But when I try to boot in bochs using image, it just executes the boot sector (gives a boot message) and then halts, not executes other sectors. But floppy works well in real computer. What may the problem be?

either you have a badly-written bootsector (which reads result depends on something specific on your PC - like the exact CS:IP value at the start of boot sequence), or you're missing bytes in your image (i.e. you only caught sector 1 or something)...

remember a PC can be booted with CS=0000, IP=7C00 or with CS=07C0, IP=0000 and check your bootsector can support both.
