I'm using John Fines bootloader, but when I try to add some code to it I and assemble, I get this error message:

bootf.asm:355: panic: errors made it through from pass one

And no other error messages! Why is this?

what the!? What assembler did you use??

Oh, should have told you that
nasm.

what code do u add and where?

/ Christoffer

The same result wherever I put it...

weird... do you have spaces/tabs before your instructions in your actual code, or are your instructions (ex "mov") at the very beginning of the line?

How about ?

Code: Select all

   mov    ah, 9h
   mov   al, '*'
   mov   bh, 0
   mov   bl, 7h
   mov   cx, 0
   int 10h

?

Still "Errors made it through from pass one"

Could you post the code so we can take a look at it?

In the readme file does it not say what the error code means or is that number a pointer?.

ASHLEY4.

never heard of such an error code either. What version of nasm is it ? did you checked for more recent/stable ones ?

0x9 and 9h are the same thing. it should not make any diffrens..

it SHOULD not. That's exactly why I asked.

I had exactly the same problem with Bootf02 and NASM the other day. I think the code I had to change was a mov bx, 0 and I replaced it with xor bx, bx and it worked ???

Hope this helps

*makes a very nice guess*

You might be *just* over the max amount of bytes in the boot sector, causing the times-thing to want to make -1 or even less zeroes padding, thus crashing nasm.
