Hi Guys,
Attached are logs from a failed attempted erase of the flash rom on the system listed in the subject. I was able to verify the flash against the backup I had taken and the system was able to successfully reboot, so it appears no changes were made. It appears this system is using a nonstandard chassis type ("Space-saving") and the: "laptop=this_is_not_a_laptop" is required for Flashrom to interact with the system. HP doesn't specify any particular process (jumper, setting in BIOS) required to update the BIOS on this system (that I could find).
Direct link to BIOS: ftp://ftp.hp.com/pub/softpaq/sp23001-23500/sp23350.exe
Downloaded file can be extracted via 7zip, then the resulting ROM.CAB file can be extracted as well resulting in 'Rom.bin' that matches the size of the chip.
7z x sp23350.exe 7z x ROM.CAB
Thanks,
Justin
