There are none, BIOS is the Basic Input Output System that allows the board to recognize the installed hardware. Please tell us what you are trying to do.
I bought a laptop from argos store in belfast
HP Pavililon g6 - 1372ea
I have no recovery disks and i was wanting to upgrade from the IDE Hdd
To a 512GB/6GB CACHE BUT I CANT SET UP AHCI MODE TO IMPROVE THE PERFORMANCE BECAUSE THE OS IS OEM PREINSTALLED WITH HP BACKUP SOFTWARE AND HP MINIMIZED INSTALL
THERE IS AN OPTION TO MAKE YOUR REPAIR ISO BUT EVEN IF I WHERE TO DO THAT AND TRY INSTALLING WINDOWS AGAIN ONLY THIS TIME PRESSING F6 TO LOAD 3RD PARTY DRIVERS LIKE AHCI, THE INSTALLATION WOULD PROBABLY STILL FAIL
