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....

Hi all,

This is my first post here (I am very new to forums!) and I hope someone can help. I am looking for a full dump of the BIOS of a HP Proliant Microserver Gen 8 so that I can get this mini server running again. (BIOS version J06 2019-04-04, chip 25Q064A).

Hi everyone,

I’m 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 – and the last 2MB in those files are just FF FF FF....

✅ What I need:

• A working 2MB BIOS dump
• Matching NM-E471 Rev. 2.0, e.g. JY575
