Hi, I flashed the bios of my friend's PC with an original Asus bios for his P5K premium WiFi motherboard, rebooted, set settings to default, rebooted again. I then flashed the bios with the modded version with asus slp and asus slic 2.1. I rebooted, set settings to default, rebooted again. But hey, the bios doesn't have the "primary hard drive option" anymore where I used to select the primary boot drive (which then used to appear in the "boot priority" option.) The missing drive is an IDE drive. There is also a SATA drive in the PC, which does appear in the boot priority list, but there is no way of making the IDE drive appear there since the bios doesn't detect it. Funny thing is, I can installed an operating system on this IDE drive by booting from windows CD, and I can even access it from the second operating system that's installed on the SATA drive. But I cannot boot directly from it because the bios cannot see it and so I cannot choose it as the primary hard drive. I have used EasyBCD to manually insert the OS that's on the IDE drive into the boot manager. However, when I boot from the IDE drive by selecting the OS options during boot, I get an error screen and cannot boot. The bios was able to detect the drive before the flash. Now here is the even weird thing. I also have the P5K Premium motherboard and I too used the same modded bios. But I can see my IDE drive and SATA drive without a problem. We both have very similar hardware. The only difference is that I have an extra eSATA external drive too. So what happened to my friends PC? I even flashed the original bios from asus back again, but the bios cannot detect the IDE drive anymore, yet the OS from the SATA drive can see and use it.
