This is the official site: support.acer-euro.com/drivers/desktop/veriton_7700g.html Actual bios: R01-C2 Mobo: I90M OS: Windows 7 I'have tried with Ami tool 1.63 ssv3 metod and i have the result in SLIC ToolKit: OEMID/tableID RSDT != pubkey = marker. I've used different brand (hp, acer, ecc.) The problem is that the OEMID is replaced but the OEMTABLEID is not replaced, pubkey and marker are ok. Have you ad idea for pathing this bios ? Excuse me for my bad english. Thanks!
