qemu emulates a whole computer system.  You basically have two different computers: a real one and an emulated one.  You're running win98 on the emulated computer system, not the real one.

The emulated computer system includes following hardware (at present):
- a Cirrus 54xx video card (which actually outputs to the qemu window using SDL)
- an IDE controller
- IDE hard disks and cdrom drives (which actually access the disk image file or device you specify on the command line)
- an ne2000 network card.
- keyboard, mouse (which actually read input from the qemu window).
- and more basic hardware that is normally part of a PC motherboard

You can get the emulated cdrom to actually read from your real cdrom by specifying the appropriate command-line parameter; I use:
    -cdrom /dev/cdrom

Instead of "/dev/cdrom" you can use the appropriate filename of your cdrom device, or even the filename of an .iso image.  The emulated cdrom is not a burner, so you won't be able to burn CDs from inside qemu.
