GRUB: Selected item cannot fit into memory!?!

Craze Frog · Post by **Craze Frog** » Thu Dec 27, 2007 3:20 pm

Ok, my kernel is 20,2 kb. I have made a virtual machine with 32 mb memory. When I try to load the kernel, grub says this:

Error 28: Selected item cannot fit into memory

If I allocate more memory to the virtual machine it works. Why is this?

Are you loading any modules?

What would be the exact contents of your multiboot header?

Code: Select all

SECTION .multiboot
ALIGN 4
mboot:
    MULTIBOOT_PAGE_ALIGN        equ 1<<0
    MULTIBOOT_MEMORY_INFO       equ 1<<1
    MULTIBOOT_HEADER_MAGIC      equ 0x1BADB002
    MULTIBOOT_HEADER_FLAGS      equ MULTIBOOT_PAGE_ALIGN | MULTIBOOT_MEMORY_INFO
    MULTIBOOT_CHECKSUM  equ -(MULTIBOOT_HEADER_MAGIC + MULTIBOOT_HEADER_FLAGS)

    dd MULTIBOOT_HEADER_MAGIC
    dd MULTIBOOT_HEADER_FLAGS
    dd MULTIBOOT_CHECKSUM

It's in elf format, so I tried without the aout kludge, but it didn't help.

What is the address your linking your kernel at?

0x00100000 (I don't have much choice if I want GRUB to load it.)
