Did you flash from DOS with AFUDOS using a USB Drive or Floppy ? It sounds like the Modded BIOS was not actually flashed properly.
Another try... I created a bootable USB Drive and use AFUDOS with Command /P /B /N /C Again, SLIC Dump tell me SLIC Version 2.0
Please Upload a R/W Everything report and maybe 911Medic or yen or some other more experienced Modder can look at that for you.
Does any body know a tool which check the SLIC Version in DOS? I think i have the answer of my problem... Edit: I Have check the SLIC via Bart PE Builder and SLIC Dump Tool and it show me 2.1 Thanks for create the Bios File, it works!
