[15:25:22] <Joe[x86]2> wtf
[15:25:24] <Joe[x86]2> well
[15:25:30] <Joe[x86]2> It loads stage 1 just fine
[15:25:37] <Joe[x86]2> attempts to load stage two
[15:25:38] <Joe[x86]2> and does
[15:25:39] <Joe[x86]2> and
[15:25:49] <Joe[x86]2> stage two prints its welcome message.. *counts*
[15:25:57] <Joe[x86]2> 10 fucking times

Oh man, I need to cut myself. I've done a lot of cutting myself lately. By the way, I hope you know I'm not serious about cutting myself. I haven't even hit my head against the wall yet.

Keep at it and soon the problem will slap you in the face and be as obvious as the fact that you smell funny.

Shut up. You know I don't like people talking about my BO issue. =(

I already fixed it. I was ret'ing instead of jmp'ing.

;D I took a lucky guess.

Good job on figuring out the problem!

[Warrior]

rofl you're such a retard joe.

[Tuberload]

It's just a joke, he doesn't have a BO problem. We're just trying to make people laugh!

Then post a picture of your mom.  Also Joe what advantage does JoeOS have over say Windows XP?  I've been thinking of down-grading to the stone age but I don't know if you are there yet.

[01Linux]

JoeOS is pre-stone age :p

[Tuberload]

Then post a picture of your mom.

Maybe you would get a laugh, superiority tends to make the jealous laugh in an attempt to keep their insecurities under wraps.

You're an idiot plain and simple.

[Joe]

yeah yeah, saying I was ahead was War's idea. =p

I screwed up my stage two loading, but I can fix it.. later!

[Warrior]

As a joke and wasn't meant to go further than a joke

[Nate]

I know its been a while but i got bored and am trying some OSDev and ill probably start my own topic but in Warrior's print function that Joe uses 'mov ah, 0x10' makes absolutely no sense.  Shouldn't it be 'mov ah, 0x0E' or maybe 'mov ah, 0x13'?

[Warrior]

To be completely honest, I havn't looked at RBIL in a while so it may/may not be right. Of course anything I program is perfect so I'd say "Working as intended" unless of course..Joe managed to screw it up.

   AH = 0Eh
   AL = character to write
   BH = page number
   BL = foreground color (graphics modes only)

Function to print, untested
(WORD) Length of the string
(WORD) String Pointer

Code Select Expand

printf:
    ; Take in the arguments
    pop ax ; String length
    pop bx ; String pointer

    ; Set the interrupt arguments
    mov ah, 0Eh
    mov bh, 0
    mov bl, 07h

    xor cx, cx ; cx is counter, set to 0

  .startloop
    mv al, [bx+cx] ;[bx+cx] is the character to print
    int 10h
    cmp cx, ax
    je .end
    jmp startloop

  .end
ret
