Title: PH67A-UD3 boot problem
Post by: JonHelgi on January 19, 2011, 12:32:13 pm

Hello, i had a problem with a PH67A-UD3.
When i cold boot the computer it freezes for a while during the bios load screen, for about 5 to 10 minutes before it continues in to bios or os.
I installed the beta bios before that and installed the os, warm boots are alright, no problem there or with the os, only during the bios load screen.

My setup is;
Motherboard : GA-PH67A-UD3
Cpu : i5 2400 retail
Memory : Mushkin 2*2GB set. BK. Frostbyte, 7/7/7/20 no increased voltage (996677)
VGA Card : Gigabyte HD9850OC-1GD
HDD : Samsung HD103UJ 1TB
DVD RW : Sony OpticArc AD-5260S
Power supply is 700W and with all of the right connectors.
Hard disk and DWD RW are connected to port 0 and 1 respectively.

I installed the F5 bios before i installed the os, warm boots are no problem, just cold ones. I could replicate the problem by turning off the computer and turn off the power on the psu then pressing the power button on the computer to clear all capacitors, wait 30 seconds and then turn the compute, it always froze for a few minutes during boot. If i pressed the reboot button it would boot into os in no time.

I installed the F4 bios and the problem went away. Boots normally now.

Just wanted the community to know of the problem and the "fix".

Hi and welcome to the Gigabyte Forum.

Well first thing to check would be wheter you have disabled the floppy drive in the BIOS along with any other devices that are not being used. Also what boot sequence have you got it set to?

There is no floppy drive on the new motherboards or any parallel ata, there is only one serial port and that is disabled.
The boot order is hard disk then dvdrom. Have tried it without the cdrom. There is nothing wrong with the harddrive, it works perfectly with the f4 bios. There is probably something in the f5 bios that causes it. Probably someting to do with EFI impimentation in the f5 bios.
It changes a little how the computer boots.

There has been an issue with AHCI/RAID in a few of the latest BIOS releases, please go back to the older BIOS for now
