Booting with Elks
Hello list,
when I try to boot the elks boot disk on my toshiba lt1200 (8086 cpu, 640k ram) I am getting displayed the error 8000 in an infinite loop. I have also tried the comb disk and a self-made kernel dd'ed on a disk, with same results :(
Can anyone point me to where this error may come from? What kind of bootloader is used on the elks boot disk? (if any) Google and a grep over kernel sources gave no hint to me yet...
TIA
Florian

At what stage? While the kernel is loading, or later (after the boot messages start to appear)?
I've just tested the latest boot disk --- works fine on dosemu, pcemu and a real PC. I don't know what the error code is, but it sounds like a floppy disk problem. You're not using a 1.44MB formatted floppy disk in a 720kB drive, are you?
(First time I've looked at ELKS for ages, actually. Wow, it's come on. It actually looks usable! What's the network code like these days?)

IIRC, it doesn't have a bootloader as such --- it uses a variant on big Linux's old boot sector system. That is, you dd the kernel directly onto the floppy disk; the first sector of the kernel becomes the floppy's boot sector, and contains enough code to load the rest of the kernel into memory and run it.

Haven'd had time yet to look at the latest version. Is the compiler now running on ELKS itself or is there still the bcc cross compiler?

ELKS is currently not self-hosting, you still need to use bcc to build
If you are feeling particularly adventurous you can also play with the turbo C stuff for user space, although bcc is currently the prefered, recommended compiler:

Can you post the exact error message you see ? Vague descriptions never help and i don't recall any "error 8000" error message anywhere in the source (grep around to provve me wrong, it's a small number of files anyway so should be over quickly no matter how slow your compilation box is).
After the bios screen I can see a clear screen and after that floppy disk led is active, loading, then only the 8000 error appears, like this:
8000
8000
8000
8000
8000
8000
etc.The floppy disk led stays active, so it seems to be like an infinite loop. And as already said, I have no reference to this 8000 number found in the kernel sources either :(

If it is register small dump (with AX containing error value) it might be that BIOS read function is returning an error, presumeably because your drive/medium is defective. Are you sure that both drive and the medium you use are working allright ?
I have MINIX successfully running on this machine, so I don't think it is hardware fault. I have only an 360k floppy drive, might that be a problem? (although the boot image easily fits there)
Thanks,
