Need help flashing my Hitachi V78

Hi, I'm trying to flash my Hitachi 78FK drive. I don't have any sata ports on my motherboard so I bought a Sata Card VT6421A
(SY-VIA-150) non raid. I installed the card, read the textbook guide and watched the tutorial video from 360 Mods. I tried both Slax disks 2.0 and 2.1 and I keep getting "port is slow to respond, please be patient" and then it just goes to the login screen. I've tried starting the 360 power at different times but no response. So I decided to try Podger's Mode B and Jungle Flasher, installed everything instructed but everytime I turn on the power to my 360 it freezes the computer until I turn the 360 power off. I tried uninstalling the VIA driver and trying Jungle flasher again, the 360 doesn't freeze the computer but jungle flasher says,"no drive detected". I've checked my bios but I dont see any thing dealing with Raid. I tried installing card to all 4 of my ports but it doesn't change anything. I don't have access to another computer to try so I don't know what to do. Thanks in advance.

Here's a little more info on my PC:
Windows XP SP2
Dell Bios Ver. 0AASNP05
VIA Drivers tried 5.3, 5.5, 5.7and 5.8 all reading as
VIA Raid Controller 3249 in Device Manager under SCSI and RAID Controllers.
