Relief that is solved off topic but

I can't find where the answer is
Before I post this topic and right just before, I gave a searching glance about via sata (vt8237R plus) in this forum

Please link the answers or explain how 2 to T-T

System Details :

Intel 531
VIA P4M800(North) with VT8237R+(South)
Seagate 7200.09 SATA2 (150 mb/s, SATA1 jumper set, Single HDD not RAID)
Windows XP SP2 with DriverPacks slipstreamed
--------------------------------------------------------------------------------------------------------

I slipstreamed DriverPacks MassStorage Drivers into WINXP SP2

After text-mode-setup finished,
before GUI-mode-setup started,
system halt (blue screen shows) saying

"Unknown hard error :
STOP:c000021a unknown hard Error.... "

Oddly, I've tried 4 times of setup changing slipstream method (1 to 2), KTD or not
Just one time I passed GUI Setup but failed normal uses (infinitely reboot even safe mode)
anyway with same method, nextime, I failed to enter in GUI-mode-setup

Unfortunately...
I also tried manual slipstreaming VIA sata-raid controller in 2 ways

1. add drivers (viamraid.sys, extras) in $oem$ / i386 , edit txtsetup.inf - pretty normal way
2. MSFN GDragoN's method, attach only 2 sys files, edit only txtsetup.inf - u might seen in msfn forum

but neither works showing blue screen

" ......... ntdl.dll error .......... " (not clearly remember)

...

Now I have no idea to figure out this SXXT problem
I feel really sick of watching my PC shut xxxx by blue screen

Please give me a hint
PEACE!

PS. Understand my stupid english. I'm not mother tongue english
