I've recently built a computer with an ASRock 890GX Extreme3 motherboard and a Samsung HD103SJ SATA HDD. I noticed on booting up that after detecting the RAM, the bios takes a few seconds to "auto-detect" the hard-drive/optical drives. I figured I could save the mobo a bit of time and effort by specifying the HDD/optical drive so it didn't have to auto-detect it, but I can't find how to do that on the BIOS. Any clues?
I've found that bit, but that only allows me to set the boot order/which drive to boot from (and I've selected the exact drive I want it to boot from). But during/after (I don't really know which one), it still counts the memory and 'auto-detects' the HDD and optical drives.
I've had a pretty thorough look through the manual and the BIOS itself, I'm guessing I can't stop it from auto-detecting. No biggie though, just thought I could speed up my bootup a little bit more
One last thing... Try to disable "Suspend to RAM" and "Check Ready Bit" (page 62 of manual). Those are last two things I can think of / see in your BIOS. If that don't help, I'm out of options on my end
