For P5B use binary from [ Ссылка ] and flash with "spipgm /s P5B.ROM" (at least give it a try, /p did not work for me)
Another good source of information: [ Ссылка ]
Try the following flash sequence:
#1 run cwsdpmi up front
cwsdpmi
#2 download current bios to safety
SPIPGM /d ORIGINAL.BIN
#3 enable bios write / unlock
SPIPGM /u
#4 erase bios
SPIPGM /e
#5 flash new bios with /s operation
SPIPGM /s NEW.BIN
#6 download new bios again for comparison
SPIPGM /d VERIFY.BIN
