Thank you for the quick reply, but I'm kind of a noob.. that's why I was asking If you could give me some pointers on how to find this 1000h block, I'd be more than happy to do it myself, the only thing is that I dont want to brick my mainboard. Thanks again
Same solution shown in above post; delete the first 1000h block from the beginning of the bios, then try to mod it using Phoenix Tool & flash using Instant Flash.
Are you sure?? Because Asus provides K54L bios for X54H. Anyway, provide backup bios for permanent modding.
