1 .Copy contents of YDL 6.2 DVD to a fat32 formatted USB Stick (you don't need yellowdog folder or ps3 folder as long as you have internet connection to ps3)
2. Use petitboot for bootloader (otheros.bld goes in /ps3/otheros/ dir)(petitboot more user friendly then kboot)
Bootloader Download
ftp://ftp.uk.linux.org/pub/linux/Sony-PS3/ps3-linux-archives/ps3-petitboot.old/ps3-petitboot-rc-08.06.27.bld
3. Prepare your ps3 and install other os from usb stick
4. Select install_ps3_480i from the usb stick when the bootloader comes up.
5. I used a http install and pointed to http://ydl.oregonstate.edu/releases/yellowdog-6.2/os/ for the install.
6. Log in as root and make a account for your daily use (password is the one you setup on install so login root and password you defined)
useradd namehere
passwd namehere
7. Type exit
8.Login your new account
9.Type startx
*If install gives you problems you can setup a http server on local pc and host the dvd from there. I completed a normal install by pointing to my windows http server (Abyss web server)*
*Useing a standard TV with the 480i will limit your desktop to 576x384 resolution. Not much to work with*
*Info about increasing your screen resolution with sdtv http://www.yellowdog-board.com/viewtopic.php?f=19&t=4283*
If anyone knows of a way to fix this issue please post
