my D975XBX2 runs really fine for me

but theres the one problem with the marvell sata controller witch makes me crazy

bios version is 2333 (found the link here in the forum, with 25xx i can't set the cpu clock to 3,2ghz for whatever reason x_X, haevn't tried the new 26xx bios yet, pc is primestable (tested 6 hrs) memtest doesn't bring up errors too)
so, there we go:
i have 6 sata harddisk drives in my computer, 4 @ the intel controller (black sata ports, inc boot drive) and 2 @ a promise sata 133tx2 pci controller (and a cd-rom + a dvd burner @ the intel ide controller)
whenever i try to attach the 2 sata drives (which are @ the promise controller atm) to the marvell controller (blue ports) my pc doesn't boot up windows (xp pro, sp2). it doesn't boot up from cd/dvd/floppy too.
the drives are recognized correctly at the bios, i can set the "boot-drive-order" everything seems fine.
after the "controller" screens "detecting drive bla bla" nothing happens.
all drives were found and after that i see a dosbox with a blinking "_" and that's all. x_X (i don't have a raid if this helps?)
i can't boot up in safe mode, nothing happens.
when i deactivate the marvell controller in bios -> windows boots
my emergency solution with the promise controller works fine, but i would like to install my wintv card in the pci slot where the promise controller is.
(other pci slot = x-fi soundcard, because i don't like onboard sound ;) )
any hints i am missing ? (boot ini incorrect? win reinstall required ? controller sucks ? new bios ? i'am too stupid ?

thanks in advance
