Re: HP EliteDesk 800 G2 Mini Bios Bin
The only difference between the PCs is the Chip.
At the none working is the chip "Winbond, 25Q128FVSQ, 1610".
I used the CH341a 1.18, AsProgrammer, NeoProgrammer and Colibri > no success.
Only with bin from post #15 i have very high fan speed, "HP mini 800 G2 DUMP BIOS_clear DMI.bin", CRC32 = 0xC44F0563, but w/o video.

Re: HP EliteDesk 800 G2 Mini Bios Bin
Thanks!
In short, one is working, the other one not!
The file "HP EliteDesk 800 35W G2_CZC6089T2G.bin" is working fine.
SN, FeatureByte, ... everything is there after apply.
BIOS update working too, it's was already with the "N21_0261.bin", but only to check.
update ME: with the Hirens Boot CD i was not able to perform the update (Windows PE). I"ll give a try after windows is installed.
unfortunately, the other file "HP EliteDesk 800 35W G2_CZC62374NN.bin"...Last edited by komser; 11-18-2023, 01:04 PM.Leave a comment:

Re: HP EliteDesk 800 G2 DM
i realized that the CZC62374NN has different chip typ with Winbound. at neo-programmer the ‘Currently selected: MX25L12873F [3.3V] 128 Mbits, 16 Mbytes’ was selected, which is correct for CZC6089T2G (Macronix). before i upload the file i check/opened it with UEFI tool. this means the read operation was successful and the file is valid?Last edited by komser; 11-14-2023, 02:15 PM.Leave a comment:

Re: HP EliteDesk 800 G2 Mini Bios Bin
maybe i have general understanding issue ... there is no generic bin file and every bin needs to be created/generated by the supporters. in others words, when i make an bin file request with my backup file, then i'll not have the mentioned issue with the blank SN?Leave a comment:

SN i'll provide later with the BIOS file request (if i'm not able to create it for myself).
the exact model name: HP EliteDesk 800 G2 DM 35W Business PC (DM = Desktop Mini)
