make bios backup with afuwin (afuwin backup.rom /O ) and then try to flash it (afuwin backup.rom /P or afuwin backup.rom )
tried another 5 version afuwin (before I used old version is 3.01) and it can flash(afuwin.exe APLITX1.30 /P) the mod without error, but the mainboard brick.
Sorry for this ... the structure of this BIOS is different from other Asrock's BIOSes Try recover the BIOS with official one
