Acill,
You will soon become an expert.
Some things thats good in Linux, of course good in any system, is to be able to load a txt config file and edit it to wanted need. So find a texteditor that You like, gedit, nano or vim or some other.
As SoundSquare writes, You can just edit the Pegasos boot menu script in a text editor. The same You can do with grub.cfg for the grub2 menu.
Load the Pegasos boot menu and edit it to something like as the examples I paste below.
Code:
case
1 of " ide:0 boot.img ramdebug" endof
2 of " ide:0 grub/grubof.modules prefix=(hd,0)/grub" endof
3 of " none" endof
endcase
For the grub2:
Code:
title Linux Ubuntu Dapper
linux (hd,3)/boot/vmlinux root=/dev/hda4 video=radeon:1280x720@70 quiet splash
initrd (hd,3)/boot/initrd.img
As You can see my script above points to hd,3. You have to change this so it points to the right partition on your set up. Likely the root=/dev/hdax must point to your Linux root partition.
The two files vmlinux as well as initrd.img are just symbolic links that points to the respectively real file. Eg vmlinux points to --> /boot/vmlinux-2.6.15-23-powerpc for instance
This means that you can always load vmlinux and it should always point to the most current installed kernel, as the symbolic link will become changed if needed when updating system.
Change directory to /boot and do ls -l and you will see all files
cd /boot
ls -l
Good luck !
