perpetual

This past week I ordered an Alfa AWUS036NHA (external USB, only 2.4GHz wireless N with AR9271 wifi chip, upgraded 9 dBi antenna as the factory antenna is only 5 dBi) interested in the range (ie. for backyard wireless) will update once its received and tested

Thanks Klem, I was able to compile chipsec sudo chipsec_main -m common.bios_wp [*] Running module: chipsec.modules.common.bios_wp [x][ ======================================================================= [x][ Module: BIOS Region Write Protection [x][ ======================================================================= [*] BC = 0x00 << BIOS Control (b:d.f 00:31.0 + 0xDC) [00] BIOSWE = 0 << BIOS Write Enable [01] BLE = 0 << BIOS Lock Enable [02] SRC = 0 << SPI Read Configuration [04] TSS = 0 << Top Swap Status [05] SMM_BWP = 0 << SMM BIOS Write Protection [-] BIOS region write protection is disabled!

Ideapad n581 owner, was able to mod bios, but running fptw64.exe -bios -f n581mod.rom got the dreaded Error 28: Protected Range Registers are currently set by BIOS, preventing flash access. does prr.exe work on this device ?

Hi!
