Let's go then.
(1) Copy all the files in the Windows XP installation CD to a folder on the hard disk, say XPCD.
(2) Extract the boot sector of the CD using IsoBuster (instructions in the link below)
(3) Copy the files in the Win98 folder of the Windows 98 CD (do not copy the folders inside) to a folder named Win98 insider the XPCD folder created in (1).
(4) Burn the files in the XPCD folder and the extracted boot sector to a blank CD-R by following the instructions in the link below.
Ignore the slipstream instructions in the link below.
Slipstream Windows XP SP2
Or, you may do what the other poster said, which is to make ISO images of your Windows XP CD and Windows 98 CD using Nero or the Mac OS X Disk Utility, and use those ISO images to install Windows XP.
