Here is a 0063 based bios for Zenith II Extreme (non-Alpha
), which has been brought up to AGESA 188.8.131.52 RC (from 184.108.40.206C) level firmware wise.
There are no changes whatsoever to the ASUS side of the code, only the blocks provided by AMD (AGESA FW stack) has been updated. Software which can display AGESA build version will indicate no change, since the readout
is based on a static ASCII string instead of true module versioning detection and obviously I didn't bother to change the build version.
- SMU 4.36.22 >> 4.36.23
- SMU PMP 4.24.16 >> 4.24.17
- AGESA Main Bootloader WABLCP9C062020 >> WABLCP04162021
- TRX40 (Bixby) Chipset FW 0.2F.12 >> 0.2F.13
- Starship Rev. B0 (SSP-B0) CPU µCode 0x8301025 (7/11/2019) >> 0x8301039 (2/7/2020)
PMU (memory controller) firmwares and their pre-configs are unchanged, so there won't be any changes in memory behavior either.
Update using Flashrom, following these
In case something goes wrong, you can use Flashback to recover, as usual.
Note that this build is totally unofficial and besides of providing the original bios, ASUS has nothing to do with it.
