I'm going to "assume" that the MoBo is "L440GX+ board" (per your other posts)?
From "Product Guide".
Adaptec AIC-7896, supporting onboard Ultra2 (LVD) wide and Ultra-wide SCSI
interfaces. Support for the Adaptec ARO-1130U2 RAIDport III card is built into PCI slot 4.
So it's a 7800-Series. Specifically, it should be in "PNPSCSI.INF". That *and* file "aic78u2.sys" (inside DRIVER.CAB) should do the trick. I fail to see why you're having a problem as those files are on *all* XP and *all* Server2k3 and are nearly identical (IOW only the DriverVer inside the INF should be different). As a matter of fact, the ".sys" hasn't changed since RTM!
BTW, mine are "Adaptec AIC-7895 Dual Ultra SCSI" and are also present, but use "aic78xx.sys".
I suggest you double-check the Driver inside Device Manager. Only thing I can figure is that your Install went horribly wrong!
