Re: Out of Range Pointer Error
Can you share your source for the .multiboot section? I assume you were trying to use GRUB2 with a GRUB Legacy header/signature?

Re: Out of Range Pointer Error
Yes, I am using a multiboot 1 header.
Here is the header:
Here is the header:
Code: Select all
[BITS 32]
MBALIGN equ 1<<0
MEMINFO equ 1<<1
GRAPHICSINFO equ 1<<2
FLAGS equ MBALIGN | MEMINFO | GRAPHICSINFO
MAGIC equ 0x1BADB002
CHECKSUM equ -(MAGIC + FLAGS)
KERNEL_VIRTUAL_BASE equ 0xC0000000
KERNEL_PAGE_NUMBER equ (KERNEL_VIRTUAL_BASE >> 22)
[section .multiboot]
MultiBootHeader:
align 4
dd MAGIC
dd FLAGS
dd CHECKSUM
dd 0
dd 0
dd 0
dd 0
dd 0
dd 1
dd 0
dd 0

Re: Out of Range Pointer Error
Thank you.
The only thing I can think of is that GRUB2 likes the MB2 header to be 8-byte aligned. I know you are using MB Legacy header, but you might try aligning it to 8 bytes to see.
Also, it shouldn't matter, but I have my video information specified in the header (not left as 0) and I can boot an MB1 header with GRUB2.

Re: Out of Range Pointer Error
Tried changing both of those things but no difference, grub2 fails while grub legacy has no issues.
The upside is that this bug disappears as soon as I make any real change. I have managed, while booting with grub2, to do a fair amount of development since this bug first appeared without any issues. I'm hoping it doesn't reappear though.
