Hey, I've been browsing these forums for months now, but only as a guest. Figured I'd sign up now, as I haven't been able to get the BIOS mod working, and no matter what I try it refuses to work. Specs: ASUS P5KPL/1600 Windows 7 Ultimate 64 Bit Problem: Unable to get to get the computer to boot from disc. (Flash drive and cd) I've tried a few different loaders, from the ASUS site, and a couple from threads on these forums. The last I tried was at: http://slics.myftp.org/Asus/ASUS_P5KPL_1600_0512_ASUS_SLIC_2.1.rar I used the "HP USB Disk Storage Format Tool" to format a 4gb usb drive, following the steps in the how to documents. (Checked Boot order in BIOS to no avail) I then tried to put a bootable .iso on a cd with a program "MagicISO", which also didn't work. The files I've been putting on are the loader exe and the modded bios (.ROM) file. Also I'm currently getting the "Windows may not be genuine" popups. Will this effect flashing the motherboard or should I install over the top without net or updates and try and mod then? I realize this is a simple problem and it is both time consuming and annoying, but I have been looking for an answer for a week now, and any help would be greatly appreciated.
