Here are complete instructions on how to insert a copy of Windows 98 into a Windows XP CD, fully under Mac OS X!
This is 100% legal as long as you own the both the copy of Windows XP Upgrade *and* a copy of Windows 9x. We're not changing the disc type from Upgrade to Full, as that would be illegal. Instead, this method combines a Windows XP Upgrade and Windows 9x CD onto one disc, so that the XP installer, sees that you have a legal previous version of Windows, without the need to eject the CD.
