ok i got chip installed can boot bios but i get errors 6 and errors 16 is there any bios that lets you boot to a dashboard ps my xbox hard drive is all messed up and neeed to format it

Any bios lets you boot to a dashboard, but if you dont have one you cant cant you.

*hint* boot disk *hint

lol i have three boots cds slayers 2.6 and 2.5 and the xbox ultimate boot cr version 4.0 none of them boot

you need to burn them to a different type of disk then lol, something that your xbox DVD drive can read.

The xbox DVD drive, im sure you know is notoriously picky about what type of disk it will read.

The majority of CD-R wont work, alot of CD-RW dont, and only the thompson can read DVD+r.

Try some DVD-R/RW.

If I remember correctly these are the most compatible kind. You could also try different brands if it still isnt working untill you find something that does.
