Going From ICH9R Mobo to ICH7 Mobo - Issues?

My 4-year-old Gigabyte GA-P35-DS3R motherboard crapped out on me (it has the ICH9R southbridge) along with my power supply, and it seems that most LGA775 boards I can find these days have the ICH7 southbridge. Am I going to run into any issues?

Here's my current setup that crapped out on me:

- Gigabyte GA-P35-DS3R motherboard (LGA 775 socket) - dead
- Intel Core 2 Duo E6750 CPU
- Scythe Ninja Rev. B CPU cooler
- 2GB of DDR2 800 RAM (G.SKILL)
- GeForce 7600 GS fanless video card
- SATA DVD Writer
- Internal USB Card Reader/Floppy Drive
- WD Caviar RE WD5000ABYS 500GB 7200 RPM SATA hard drive for OS and software programs
- Seagate Barracuda 7200.12 ST31000528AS 1TB 7200 RPM SATA hard drive for data
- Corsair HX520 Modular Power Supply - dead

When I built the computer back in the fall of 2007, I set up the ICH9R southbridge to run in AHCI mode. If I am understanding correctly, the ICH7 chipset does not support AHCI... am I mistaken? If this is correct, will I run into any problems if I simply connect my two hard drives to the motherboard SATA headers and turn the power on?

Thanks in advance. Sorry if this is a total newb question. I have not kept up with computer technology in the past 4 years since my system ran without issue.

AHCI starts around ICH6. If it is not the base ICH7 or ICH7-U, then you will have it.

All I can tell is that the motherboard I bought:

ASUS P5G41T-M/CSM LGA 775 Intel G41 HDMI Micro ATX Intel Motherboard

Says that the soutbridge is ICH7. Can anyone confirm if I will have AHCI capability? If not, what will happen when I swap this motherboard into my PC and turn on the power? Are there some settings I need to set in the BIOS of this new board to avoid a critical hard drive crash?

Thanks in advance!
