@ moderators: I've checked his mod and suggested to correct the checksumbyte of SLIC. You may close the thread!
a little question: to uncompress .wph what utility you have used? i tried to open B26-120.wph acer bios using phoenix editor and give me the error: invalid lenght ROM.
no way. I have v2.2.0.1 and also v2.2.0.0. Same result: invalid ROM lenght. ROM is for ACER ASPIRE 5020
