Bootloaders (yaboot specificaly)

has anyone used this? and if so here is the situation i have an imac bondiblue and i installed 9.2.2 and when i did hat i parted the hard drive to a 2gig mac and a 2 gig linuxppc prefered format that was working fine but when i installed os X after that i installed fedora core 4 and it was still working fine.

So like 2 months later i needed to update some software off cd and yaboot didnt want to boot the cd and so i just held the "c" key right booted fine got it installed didnt use it til like 2 hours ago and i cant get into the bootloader i dont want to format the drive less it is the only option my gf spent 3 hours making here background image on it.

all i want to do is to boot into fedora core and copy that file to my other linux box and format the entire drive in my imac and run just a single os or just net boot it.

in os X cant you select the other partition to boot from?there should still be a bootloader on it just no reference to it from the first partition

no the mac doesnt see the linux and the linux doesnt see the mac.

You need to reset open firmware.
Something like: setenv boot-device hd:x,\\tbxi
You need to know what partition yaboot is on. For more info, go to your linux distro's web site or here: http://www.yellowdoglinux.com/support/solutions/ydl_general/boot_functions.shtml

i thought there had to be a comand to do that i just didnt know what it was
thank you

i got it fixed i think that link helped but i finaly broke down and just went back to 9 cause i have no need to run ten it is to much of a drag on my system.

but i deleted that and i guess i dont have a viable os 9 folder so it went to the loader and now i just need to fix whatever is wrong with the freaking fedora install.
