[LinuxBIOS] SST49LF004A/B chip is not detected in MSI MS-7250 VER:2.2 (K9N Ultra) Motherboard

[Kiran Patil]

Hello,

MSI MS-7250 VER:2.2 (K9N Ultra) motherboard is not detecting
SST49LF004A/B chip.

I am attaching the following files,

flashrom.log -- Which contains flashrom --verbose output

lspci.log  -- Which contains lspci output

Thanks,
Kiran.

It seems we are missing a board enable routine for the K9N Ultra.

But the motherboard detects Pm49FL004 chip.

Please find the attached log file.

Are you absolutely certain that the chip is an SST49LF004? You aren't
using a BIOS Savior with a switch in the wrong position? I know this
sounds a little odd, but here's the deal: the flash chip vendor and
model that flashrom is reporting aren't anywhere near what they should
be for that chip. So, either you have a different chip, or else the
board is somehow masking the chip ID, and reporting a false one. It
could be that the board is somehow disabling access to its own flash
chip, and instead copying the BIOS contents to ram (although the more I
think about it, the more far-fetched and maybe even impossible that
sounds). Do you have a floppy drive that you can use uniflash to try to
flash, or at least identify, this chip?

Thanks,
Corey

Yes I tried it on ASRock motherboard and it is detecting. I am not using
BIOS Savior,  instead I am removing the Pm49FL004 chip and inserting the
SST49LF004A/B chip in the Bios socket and after that using flashrom utility
to do further operations.

Thanks,
Kiran.

Is it a SST49LF004A or SST49LF004B? You have to look at the numbers
printed on the chip.

The SST49LF004A variant is FWH only, but the Pm49FL004 is FWH+LPC
capable. That (chip not designed for the board) might be the source of
the problem.

We have SST-49LF004B (33-4C-NHE 0710022-CA) chip.

Can you read out the Pm49FL004 chip on the MSI K9N Ultra and flash that
image on the AsRock board to the SST49LF004B chip? Then plug the SST
chip in the MSI board and try to boot from it. If that works, try
flashrom again without changing the chip.
