Ska uppdatera bios

Ska uppdatera bios i min data, mitt mode kort är K7VT4A+
jag hittde bios på deras hemsida och det står så här:

Create a bootable system floppy disk.
Download an updated ASRock BIOS file (WinZip format with .zip file extension) from the web site, unzip the BIOS file and save both ASRFLASH.EXE utility and BIOS file to the disk you created in step 1.
Boot from the disk you created in step 2.
At the "A:\" prompt, type ASRFLASH, hit space bar once, and type BIOS file name then press <Enter>. For example: A:\ASRFLASH K7S41GX2.00 <Enter> then you will see a message "Please wait for BIOS loading ROM".
After 30 seconds, you will see the message "Flash ROM Update Completed - Pass", then you have finished upgrading the BIOS.
After finishing upgrading the BIOS, please remove the floppy disk. Restart your system and press <F2> to enter the BIOS setup utility during boot up.
In Exit menu, please select "Load Default Settings" and press <Enter> to continue.
Select "Exit Saving Changes" and press <Enter> to exit the BIOS setup utility.

(At the "A:\" prompt, type ASRFLASH, hit space bar once, and type BIOS file name then press <Enter>. For example: A:\ASRFLASH K7S41GX2.00 <Enter> )
