The motherboard is an ASUS P5N-E SLI. I don't really know what a RAID array is, (but I think that it requires multiple hard drives) nor what FreeDOS has to do with anything; I am ignorant regarding many aspects of computers, but am trying to learn. I only have one hard drive, if that helps. After installing XP and during the installation of the motherboard software, I see a screen saying:
"Welcome to ASUS Motherboard Make Disk for DOS Menu
Rev.1.0
1) NVIDIA RAID Driver Page
2) JMicron JMB36x RAID Driver Page
3) FreeDOS command prompt
Please choose 1 ~ 3:"
I posted here because this is on an XP machine, but maybe I should re-post on another part of this forum (?) I mentioned that about the "a" drive because during at least one of my multiple attempts to install everything, the computer kept looking for a disk in the "a" drive. The external floppy disk is seen as the "b" drive, but I don't know how to do away with the non-existent "a" drive.
