That would be nice of you :)

So I ordered 5 blank rom chips and they arrived today at my place. So
i decided to experiment with them right away. As you can guess i do
not have access to a rom writer device or whatever you call these
machines. So i have to rely on hotflashing.

I first read the original bios from the rom chip
Pulled out the chip (pushpin method works great), dropped in a
replacement, erased it (flashrom -E), tried to write the original one
in it (flashrom -wv original_bios.bin) but the last step always ends
with a "FAILED":

root at kopiluwak ~/bios/flashrom # ./flashrom -wv ../original_bios.bin
Calibrating delay loop... OK.
No coreboot table found.
Found chipset "Broadcom HT-1000", enabling flash write... OK.
Found chip "SST SST49LF080A" (1024 KB) at physical address 0xfff00000.
Flash image seems to be a legacy BIOS. Disabling checks.
Programming page: 0250 at address: 0x000fa000
Verifying flash... FAILED at 0x000f0000!  Expected=0x00, Read=0xff

So I'm a bit stuck... Seems like there are motherboards that need
special modifications of flashrom to actually work? I assume Mondrian
has a rom writer device thing, so you prolly didn't encounter this
problem. But if you did... or if you have a clue on what is going

Kind Regards,
