I looked at it and it seems maybe the last 4k comprise checksums and perhaps signing by ASRock. Self-consistency (plus perhaps an unclonable physical factor, hooray!) Still...it hasn't worked? Anyone?]]> Wed, 10 Jun 2020 05:22:41 +0000 https://forum.asrock.com/forum_posts.asp?TID=14572&PID=76303&title=fm2a88xitx-rom-are-fatter-than-8mib-whaaa#76303 https://forum.asrock.com/forum_posts.asp?TID=14572&PID=76110&title=fm2a88xitx-rom-are-fatter-than-8mib-whaaa#76110 Author: AMD-fandom

I managed to get a FM2A88X-ITX+ to stop booting by presenting a 3.4 ROM on a flash drive. Attempts thereafter to burn the ROM have met similar fates in that the mobo will power up with no beeps and do nothing.

I have a programmer (CH341 jumpered to 1.8V devices plus a utility) but I find that the binary image is 8,392,704 bytes rather than 8192ish, so it seems that it's not the binary or the first few kb are trash. What offset should I be starting flash with? Is there a magic number at a certain location I can take as a cue?

For example the 3.4 ROM starts with ?¹Â?J#wûH but at $0x00021000 there's another block of data, perhaps the load of UEFI image should be offset to that?


Maybe there's a binary viewer or ghidra environ I should load it into...
