I had the same problem, below was my original post with the solution - and if you need to flash any Samsungs, I have the hexedited mtkflash to work with this chipset
Hallelujah!
The end of failure road has been reached!
I have successfully flashed my
Hitachi v47 with the
VIA VT6421L chipset on the infamous
SYBA SY-VIA-150 PCI SATA /IDE Combo Controller Card, Non Raid from
Newegg (remember that $15 pci sata card which everyone said worked but forgot to say it was meant for flashing Samsung drives) - Before I go along with my procedure I would like to thank
jameswalter, and ikecomp for telling me it
really was possible to flash
Hitachis with this card and how they did it. Also,
Hopeful and Gazcoigne had extremely helpful alternative information and recommendations - so thank you!
I can't guarantee this procedure will work for you, and this method is only recommended to those who screwed up and bought the promising card from Newegg to only find they waited 3 days for nothing! The following are my
exact steps and please keep in mind I do understand that shortcuts are most likely possible:
Step 1
Install the card and boot up Windows XP. Once loaded, insert the driver CD that came with the card and navigate to our driver directory (first one in /VIA/) and run the setup. Once finished, reboot the PC.
Step 2
Click Start>Run and type in
msconfig, click on the Startup tab, then find the VIA RAID Tool Utility - raid_tool.exe and uncheck it>click Ok and then click
Exit without restart. Next, download the latest driver for the card,
Available Here, unzip the package and run the setup. Once finished, reboot the PC, check the box to
not see the
msconfig notification utility anymore, verify the VIA RAID Tool has been disabled, and then shut the PC down.
Step 3
Make sure your 360 drive is setup to be thrown in modeb by the 2-wire trick (sorry SLAX cd doesn't work with this card) (
2 wire trick tutorial - page 39) and make sure the SATA data cable on the drive is setup on the
primary connection (the one furthest away from the back of the case). Now, with the 360
off boot up the PC and as soon as you see the Windows loading screen, wait for the green status bar to move
half-way across the screen (it will do this many times but the first time is what we're concerned with) and turn on the 360 while holding the 2 wires/resistors together until the xbox green light flashes rapidly and release the 2 wires/resistors. If you did everything correctly, wait for XP to boot up and the drive should
now be detected! If it isn't - don't be discouraged and simply try starting your 360 at different times in the Windows boot up process.
Congratulations!
You may now continue flashing your drive however you please, I personally have used the Xtreme 1.2r1 package with great results (thanks to GaryOPA) - I leave the rest to you seeing as everything else seems relatively straight-forward
Best of luck to all with the VIA VT6421L chipset on PCI adapters - just remember all those who
actually have found this helpful information out, I simply am reguritating it
This method has worked for me and may it work for you!
