I have an old t4400sx laptop and trying to upgrade the HD does anybody know where i can find v3.5 bios for this machine. I have tried Toshiba and have serched the web high and low. Any help would be greatly aprecieated
If the chip is standard EPROM (brown chip with window covered by label), it can be erased and reprogrammed in external programmer - you need the BIOS image file for that. If it's PROM (non-erasable), you can buy blank EPROM and program the new BIOS there (or have it programmed somewhere).
