QEMU Error 28: Selected item cannot fit into memory

[elijaheac]

Hi, I'm following the Bare Bones tutorial on the wiki (I'm using NASM, by the way). However, when I launch it in QEMU and type in

Code: Select all

kernel 200+18

I get the following error:

Code: Select all

Error 28: Selected item cannot fit into memory

I have tried Bochs too, and it doesn't give an error, but it freezes the open TTY device. I can switch to another, but the TTY device with X freezes (I can move my cursor around but it won't click). What is wrong and how might I go about fixing it?

Thanks in advance,
elijaheac

How big is your kernel? Doesn't it need to be under 510 bytes? (At least the first stage of the bootloaded...)

Are you using an ELF binary? Is it higher-half? Do you use the physical address hint? (in the linker script - AT( ADDR(.text) - kernel_base ) )

Also, that method of loading is a hack, get a grub image with a filesystem instead.

I'm just following the tutorial, It is not higher half, it is ELF (I am on Ubuntu), and I do not use the physical address hint. I'm saving optimization for later. First I just want to get the base kernel running.

I'm just following the Bare Bones tutorial. it shouldn't be any larger or smaller than the tutorial kernel.
