Hi everyone,
Iām looking for a 2 MB BIOS dump for a Lenovo IdeaPad 5 16ARH7H / Legion 5 with mainboard NM-E471 Rev. 2.0.
The BIOS chip is a Winbond W25Q16FW (1.8V, 2MB) and it's completely unresponsive / bricked. I tried recovery via USB but no success. Now I want to reflash it externally using a CH341A programmer.
I already found 32MB dumps (e.g. from Vinafix and Badcaps), but they are too large for the chip ā and the last 2MB in those files are just FF FF FF....
ā What I need:- A working 2MB BIOS dump
- Matching NM-E471 Rev. 2.0, e.g. JY575

Hello all,
I have a Lenovo Thinkstation P500 that is stuck at post with no display, it happened after I changed the memory timings in bios. I can not clear CMOS using the jumper on the motherboard, also tried re-flashing bios suing a USB stick but it also doesn't work. The only solution that I can think of right now is re-flashing the bios chip using an external programmer but the problem is that I don't have the bios dump of p500 for flashing externally and I don't know the location of bios chip. If someone can provide the bios dump and bios chip location it would be really helpful.... -
Lenovo X1 Carbon 7th Gen Type 20R1
SN: PF1Y5BBJ
Board: GX490 NM-C661 Rev: 1.0
I have made two dumps of this bios, with the bios chip removed from the board and the hashes match on both dumps, but I cannot find the DMI information in the dumps except for the Windows product key, so I think it is corrupted. I have downloaded two bios updates from the Lenovo support site, but they contain small .PAT file, and 4 subfolders containing .FL1 and .FL2 files, which I don't understand enough to figure out how to use to fix my dump.
The problem with the laptop is that... -
Hi, I hope this is the right place to post this. This is my first post on this forum.
A friend helped me get a prototype Lenovo motherboard from China, it's got a hole drilled in it but I'm working on trying to revive it to some degree. I dumped the bios in hopes that it might be useful to someone, since this board is configured with the 3rd NVMe SSD slot and maybe it is useful as a reference for modding another bios to support this function. For example the M90q Gen 2 / P350's unpopulated 3rd NVMe slot footprint maybe.
This bios dump is straight from the chip, nothing has been... -
Hi, the SIO firmware flash in my lenovo P720 seems to be corrupted, after a reboot POST fails with CPU1 fan failure and all fans set to max, proceeding with booting shows SIO FW no response.
I've tried using the lenovo sio update utility but that fails with "EC Autho Value not Match" when the system reboots for the update. The efi update tools has a S04FW.cap file but it's 256kb which seems too small?
