I think a GATEWASYSTEM string did not get changed. I would be curious about the RSDT and SLIC OEMID strings... I have changed a couple lately...
The readme-file included in the 7720 BIOS says: Model: Extensa 7220 Extensa 7620 Extensa 7620G Extensa 7620Z TravelMate 7320 TravelMate 7720 TravelMate 7720G The readme-file included in the 5220 BIOS says: Model: Extensa 5220 Extensa 5620 Extensa 5620G Extensa 5620Z Extensa 5620ZG TravelMate 5320 TravelMate 5720 TravelMate 5720G But all the files are the same. Hmm...?? To flash (and risk a brick) or not to flash - that's the question
No idea how I missed that one! Many thanks for the mod (and the reminder!). I'll give it a whirl and report back.
