|Yeah, probably best to install XP directly but if you do install 98 first, remove as much ram as you can. The 512 meg is not an absolute limit and you may be able to do the install with a gig of ram. But you can't run 98 successfully with more than 512 unless you make the adjustments Mickliq mentioned.|
Also with 98 first edition there's a problem with cpus faster than 2.2 gig:
And there's a problem with 98 scandisk and I think defrag and maybe other utilities on partitions larger than 127.53 gig:
Any or all of the above may be contributing to the problem.
Real men don't use AntiVirus; they just reformat
