BIOS image for T500 with MX25L6405D chip

[Thinkman0512]

Hi,

I'm trying to de-libreboot a T500 which sadly didn't come with the original BIOS file. The ones I've tried to use from the internet all didn't work, because flashrom complained about them not being the exact right size. Complete BIOS files are too big (8.3 MB vs 8192 KB) and trying to flash only the .FL1 file from the updater doesn't work either, because it's too small (4.2 MB vs 8192 KB). I really don't want to tear the T500 apart and hardware flash it if possible, but at this point I don't really know what to do anymore. Do any of you guys know what could be the issue?
