"Here are some of the details.
SYBA controler card- silicon image SIL3112A Serial ATA."
I have the Silicon Image 3112 controller for my Samsung SATA drive.
If you are installing Windows XP for the first time on this computer, XP will prompt you for additional third party SCSI or other drivers - it will actually ask you to push F6, at which point, it will appear to blow right by. Eventually, Windows will recognize that there was no parallel ATA drive and ask you again for the driver for your SATA drive. Hopefully, you have a 3.5" floppy drive with the appropriate driver. I looked up your mobo on NewEgg, and it does not appear to have the floppy with the retail box (but hey, pictures can lie).
Also, ensure that you have the SATA power cable to the drive, as well as the SATA data cable which attaches to the controller on the motherboard. There are no jumper leads that need to be in place for SATA, but you may need to check your BIOS to enable the SATA controller.
Let us know how this works out for you, or if you have further questions.
Update: See if the controller is included on Gigabyte's site here:

Have to run to a dinner party, but will be back later on.
