help w/ pioneer ao5U installation

[whokilledcyrus]

i need y'alls help. i just installed this dvd-r writer by replacing it w/ my sony cd writer. i also have a regular dvd-rom drive on my computer. when i turned on my computer it booted straight to my desktop as if there was no detection of the new writer or any problems that were detected. i clicked on system properties and there's a yellow flag on "second IDE controller(dual fifo) which is located under "Hard Disk controller". i'm going to reboot my computer again hoping this could help. btw:

win 98
128 mb ram
13 gb harddrive (7.5 gb free)

i appreciate your help.

ps. i placed it as a slave, while my regular dvdrom is the master.
