In Intel systems the flash chip is directly wired to the PCH, and it can be accessed by an Intel utility called Flash Programming Tool. BIOS region of the flash memory must have write permissions The requirement for it to work on a system are the following: It's a very powerful application which supports the most common flash memory chips. The OEM or BIOS vendor omitted to set an additional flash lock. You can't flash an encapsulated firmware image, only the pure bios region. You will have access to the BIOS region for obvious reasons, but the second point can only be figured out by trying to flash a BIOS.
If the tool comes up with an 'Error 28', download the attached 'prr' utility, as well as the DOS version of the flash tool. Put both on an USB drive which can boot DOS, boot from it and execute the prr.exe, if it manages to remove the protection on your system it will tell you 'ready to flash', in this case go ahead and directly flash with fpt, without rebooting before doing so. If prr can't remove the protection you're most likely out of luck, even though might be ways for certain systems, but the chances are pretty small. You only want to update the bios.ĥ383 5384From: On Behalf Of Kiet Pham Sent: Thursday, Octo9:45 PM To: Subject: Re: Using Flash Programming Tool cause Flash Access Error In order to flash a BIOS you will need to remove the capsule from the firmware image provided by your system manufacturer.
