How does Linux "see" a hardware RAID controller

....and it's attached hard drives?

Pardon me for sounding like a total dweeb, but this is my first experience with Linux (I'm a windoze person).

Here's what I've got - I have a computer loaded with Red Hat Linux Enterprise WS (kernel 2.4.21-4.EL) that I'm trying to set up disk mirroring on for redundancy reasons. The PCI card I'm trying to use is a Promise FastTrax 100 TX2 (no, it isn't on the Linux HCL, and as such, there are no drivers for it).
Anyway, after installing the card, I was able to get into Promise's FastBuild utility to build the mirrored array (successfully). Upon reboot, the system came up fine, but when looking in hardware manager, there are two devices listed under Hard Drives. In Windows (if you browse My Computer), it will only show one drive. The Promise card is recognized if I do a lspci | more from a terminal session. I am looking for assurance that I set this up right and data will be successfully mirrored between both drives. If I did it wrong, please knock some sense in to me.

Mant thanks in advance.
