Here's what i got from my computers technical manual. its an MB-8500TUC
here is some info on it.. not sure whats really relevant. i just wanna make sure the 30 gig HD will work. My friend is reluctant to let me open it up and try unless its worth it.-supports 2 USB ports
-supports cpu bus clock from 50mhz to 66 mhz
-supports 25/30/33 mhz pci bus speed
-supports dram memory up to 128mb on board
PCI Enhanced IDE Built In on Board
-supports 4 IDE hard disk drives
-supports mode 4, Master Mode, high performance hard disk drives
-supports IDE interface with CD-rom
-supports high capacity hard disk drives
-supports LBA mode
i took these lines straight from the motherboards manual. hopefully this helps. thanks a lot.
