|The memory issue running Win98 when more than 512MB of RAM present can be overcome with a registry entry. |
The other issue with running Win98 on a modern system has to do with the chip set drivers. Some of the subsystems like PCIe may not have any Win98 drivers available.
Run Windows 7 pro or Ultimate and you can download and run Virtual PC which allows to to download a free virtual copy of WinXP in Virtual Mode. It runs inside Windows 7 without a reboot. Works very well.
If you are running a lesser version of Windows 7 you can perform an inplace upgrade to Pro or Ultimate without a re-install.
There are some hardware requirements which most computers meet. Some laptops do not.
You WILL need more than 1GB of RAM to run Virtual PC.
