GA-X58A-UD3r (rev. 2)- DVD Drive no longer recognized by the BIOS

[Alexko]

My DVD Drive is no longer recognized by the BIOS (Version FA - shipped with the board) even though Windows 7 x64 recognizes the Drive. 

Built a new PC (first build; configured the BIOS to run in AHCI mode and loaded the AHCI Chipset drivers in the iMSM/64-bit folder for the ICH10 controller during OS installation when prompted). Installed Windows 7 x64 and chipset drivers from the supplied CD, and PC was problem free. DVD drive is in SATA port 1 (SATA2_1) and the Hard Drive is in GSATA3_7. I am not overclocking.

Due to problems with a creative labs driver when I installed an Auzentech Xfi-Forte sound card (BSODs upon startup and shutdown associated with CTaudSVC process), the easiest thing was to just reinstall the operating system and start over since this was a new installation.

Upon attempting reboot and reinstallation with the Windows 7 disc in the DVD drive, the computer was unresponsive when trying to press any key to boot from CD or DVD ROM (to reinstall Windows). Upon checking the BIOS settings, the BIOS no longer recognized the DVD drive, so I cleared the CMOS (then saved and exited), loaded optimal defaults, changed the BIOS setting back as they were to support AHCI, and let the PC reboot. At this point, the drive was recognized again, but when I tried to reboot and reinstall again (with the Windows 7 disc in the DVD drive), the computer was again unresponsive when prompted to press any key, and the BIOS settings again indicated that the DVD drive is again not recognized.

To help with trouble shooting, here are the integrated peripherals BIOS settings I changed:

ICH SATA Control Mode - AHCI
SATA Port0-3 Native Mide - enabled
Azalia Codec - disabled
eSATA Control Mode - AHCI
gSATA 6_7/IDE control Mode - AHCI
GSATA 8_9/IDE control mode - AHCI

System specs:

GPU: XFX HD-5850 Black Edition (HD585XZNBC)
CPU : Intel Core i7 930     
OS : Win 7 64-bit       
Memory: 6 GB OCZ3G1600LV6GK
Power Supply: PC Power and Cooling 750 W
DVD Drive: Sony Optiarc AD-7261S-0B
Sound card: Auzentech X-fi Forte 7.1
Western Digital Caviar Black 1.5 TB

 Not sure how to further troubleshoot this, and any help would be appreciated. Thanks in advance for any help.

Have you tried pressing F12 as you are booting to get the boot option?

[Alexko]

Thanks for the reply.

No, I have not tried F10. Where will that take me in the BIOS when I press it? Do I press it instead of delete to enter the BIOS? I am famliar with F12, but nor F10...

[Dark Mantis]

No my typo I have edited it now to F12, sorry. I would try disabling native IDE mode as well and see if that helps.

I have the BIOS set to boot from CD-ROM first, so will F12 overrride that and enable booting from the optical drive? I will try disabling native IDE mode, but will this cause potential IRQ conflicts?

Thanks!

[Dark Mantis]

F12 will allow you to pick which drive to boot from for this time only.
Disabling Native IDE mode will help by stopping any IRQ conflict that may be happening eg with your sound card I am hoping.

[Alexko]

F12 allowed me to select the boot drive, but the DVD drive was still unresponsive. I also disable native mode, but that did not help either.

What is the state of your disk and is it a retail copy?

What is the state of your disk and is it a retail copy?

The disk is a pristine OEM DVD (system builder's version).

Ok. Let's go back to the basics. Can you try a new sata cable and check the power cable is making a good connection?

The power cable is well connected (and the drive spins when window is up; I was able to play a game). I will try a different SATA cable and post back.
Thanks!

[Alexko]

New SATA cable made no difference. Also tried SATA2_0 port, with no luck.

Happy to report that I found a solution. Since loss of keyboard control during the boot sequence was pointing to a potential keyboard issue, and I noticed a setting in the integrated peripherals section of the BIOS to enable legacy keyboard support, I enabled it, and was able to access the DVD drive during boot! I'm not sure why I had keyboard support during the original install, or why the DVD drive no longer shows up on the BIOS. But things work normally now and I will reinstall Windows as planned. Thanks again for all of your help.

Happy to hear that you found the answer to your problem in the end and glad to be of help.
