Enough of the title, let's get down to business of this wierd problem.
Ok, the facts:
Asus K8V-SE Deluxe
builtin SATA controllers, 1x VIA VT6420 (VT8237) & 1x Promise FastTrak 378
Got 2x sata drives on via, 1x sata drive on Promise.
standard ideports got 2x drives and 1xdvd.
Plugged in Promise Ultra 133 tx2 with 2 more drives.
After this i got my problem.
In boot i do not see my FT378 scan for drives anymore and thus i cant see my FT378 drive anymore.
Unplugged the Ultra133 card and now it's fine again, except i cant use the ultra 133 card and my 2 other drives.
When the ultra 133 card is plugged in, i can boot into windows fine, fire up device manager and i see FT378 with a yellow symbol and the message "device cannot start code 10", again i dont see it in boot anymore, not even in BIOS.
It feels like the Ultra133 pcicard is canceling out the onboard fasttrack controller, the computer only boots 2 BIOSControllers as it seems.
Loads VIA -> Loads Promise FT
if Promise Ultra plugged in
Loads VIA -> skipping Promise FT -> Loads Ultra133
Anyone that could shed some light on this ???
