No.
What I am saying is that you have two options.....
Option 1:
Take your broken box, which if I am understanding has a modchip with no BIOS on it, and load a BIOS to the modchip. Follow whatever the manufactures instructions to do this are.
Then use the Slayers disk to reinstall your HD with the nec. software.
If this chip requires a woking box to flash, then you're stuck with option 2.
Option 2:
Take your working box, Hotswap the HD to your PC (If the drive is not locked you don't need to hotswap just hook it up), and use HDD_Driver or XLinux to back up the HD.
Then take your broken box, hotswap the drive to your PC (This drive WILL be locked so you must hotswap), and restore the drive with the backup you made.
This option will only work if you have not modified the xboxdash.xbe on the working box. If you have, it may be a good idea to put the original one back before you make the backup.
And just as a general rule of thumb, anything that includes the word "Format" followed by a drive letter that you intend to keep the data from, is best left alone!
