every time i flash my bios (i made a slic 2.1 and slp 1.0 hp with award tool) i dont get any "SLIC Table" with slic toolkit 3.0.
Make sure you don't use any crack or loader now. If you have, uninstall it with voaktool 2.5., Loader may interfere bios modd that may cause wrong information about your slic.. Clear CMOS and set bios setting by default after flashing.
It depends a lot on the make and model of your MB, which we don't know. Every MB has specific method that works best.
On the ASUS web site they list P4S533-VM, P4S533-X, P4S533, P4S533-MX and P4S533-E. No P4S533-VX listed. Is it an OEM MB made for a company like HP or Sony ? A link to the original Un-Modified Bios would be helpful. That would let me look at it for you.
