Thunder K7X (S2468) BIOS

  Current BIOS Revisions

For new BIOS versions (v4.03b or above)


Boot Disk - Refers to either a Windows 95 or Windows 98 boot disk. Any other type of boot disk might load memory resident programs which will interfer with the flash process. Make sure you hit the F5 key when the boot disk first starts running to make sure no other programs are loaded in the back ground without your knowledge.

Bios Flash Package -  Unzip the entire bios package to a seperate clean floppy.  Insure there are 3 files that are unpacked during the unzip process


Two separate diskettes are needed. The first diskette is the Windows 95/98 Boot Disk. The second diskette should contain the 3 files needed to flash the bios.  These files are provided when you unzip the bios flash package from the website.


At the A: prompt simply type in "
flash" and the rest will be handled by the files included in your download.

For previous BIOS versions (below v4.03b)

You must use the "phlash16 " BIOS flash utility (from link above) for Thunder K7X.
You must use a Win98 DOS diskette or newer. DOS 6.22 will not work.
To flash the BIOS, type: phlash16 biosfile.rom
