I need some help with modifying Firepro Tonga card.
What I have (MXRT-7600 which is oem version of W7100)
What I want to be (FirePro S7150)
They are identical card from visual perspective.
W7100 = 0x692B
MXRT7600 = 0x693B
S7150 = 0x6929
When I flash MXRT 7600 rom, I get DeviceID = 0x693B (same as bios)
When I flash S7150 rom, I get DeviceID= 0x692B (It should be 0x6929)
I modified bios of both 7600 and 7150 to see if it changes.
I changed right after 'PCIR' and I was able to see changed DeviceID during atiflash.
But even after reboot, DeviceID still remains same as before modification.
What I dont understand is why DeviceID become 0x692B when I flashed 0x6929 BIOS
Is there ASIC lock that overwrites DeviceID? or ATOMBIOS command that sets PCIID?
I attached both BIOS
