Machine type 5049
Product ID: 5049BQ4
Motherboard: Lenovo IS6XM REV1.0, FRU 03T8182
Flash BIOS update - ThinkCentre M81, M91, M91p / ThinkStation E30 said 9hj958usa is the latest release of BIOS but I remember that the latest 3 word were AUS, not USA.
Was donated but suffered some voltage drops after which he did not boot. Only 2 long beeps followed by a continuous string of 2 short beeps.
In the end I tried to put several variants of bios dump found with a USB CH314A SPI programmer but nothing happens.
I used AsProgrammer_2.0.3a, CH341A Programmer from 1.18 to 1.40 or flashrom.
Strange things there... flashrom detects WINBOND W25Q64CV bios chip with the clamp pin 1 to pin 1 bios chip position, the other programs find the chip with the pin 1 to pin 8 position. I don't even know how to choose ...
Each program variant needs a certain driver variant.
Quite difficult to manage without having a full working version of bios.
Thanks in advance
