@serg008 I'm sorry. Tried the original R02-B1 few minutes and it told me that it doesn't match my product number (some sort of that). I guess only R01-A1 would work for me. Thanks for your efforts so far.
Try this: Acer_Aspire_M5100_R01-A1_ACER_SLIC-SLP_DYNAMIC.rar megaupload.com/?d=SISBP9IN Flash original bios before the modded one !! Confirmed working by tester9.
