Lowlevel-Coding / No bootable device.

« am: 31. August 2009, 01:11 »

Hallo Leute,

ich habe nun das Problem dass Bochs bei meinem Kernel einfach "den Löffel abgibt" und meint, es wäre "kein Medium" eingelegt.

Ich hab mir mein OS via HexEdit angeschaut und es sind sehr viele Leerstellen (00) drin?!

Lowlevel-Coding / Bochs spinnt?

« am: 03. May 2009, 00:20 »

Hallo Leute,
Wenn ich Bochs benutze, dann kommt da entweder dauernd
read_virtual_word_32(): segment limit violation

oder dass er das BootMedium nicht gefunden hat.

VMWare zeigt auch nur noch nen schwarzen bildschirm statt ein bisschen text.

Egal ob ich versuche den ProtMode reinzuhauen oder nicht...

Edit:

Mit dieser Config gehts :
