bios Update problem

Hello, I just built me a computer using Msi mother board. Everything seems to be working fine except I thought about a bios update. Anyway, I went to: http://www.msi.com.tw/program/produc...3&NAME=MS-7104
I updated my bios. However, it still booted up, but of my hard drive, cdrom, & floppy were seen in the bios, but was not usable when system was finished booting up. I went to system info and there a yellow exclamation beside the ACPI in the system device (hardware manager). I tried updating again, but the floppy was not available to use. What could be done at this point? Any suggestions? (PM8M-V MB)
