I was unable to find a satisfactory discussion of setting up Windows 98SE (and Windows 98FE) on Parallels Desktop 6. After a day of fuss, I finally hammered out what I believe is a solution to the issue. It involves some steps from this forum and elsewhere, coupled with a few "new" things. This post will take a while to complete as I am busy and have to complete it step-by-step. Please be patient. NOTES: I post this since it worked for me, however I make no assurances that this will work or be safe for everyone. Please use discretion... Also, if someone else already posted this, I apologize. I could not find the Parallels 6 solution using search. Problem description: Windows 98SE guest OS exhibits one or more of the following issues upon installation in Parallels Desktop 6. 1) IRQ conflict prevents the network adaptor from starting, killing internet access on the VM 2) Sound does NOT work, and attempts to use the usual driver locks up the VM upon shutdown and boot. 3) Video driver needs installation (already addressed elsewhere, but I post again to be complete) 4) USB does not work (at all) I will provide step-by-step (verbose) directions for those of you who are not familiar with legacy windows oses so you can get an operable Windows 98SE VM on your Parallels 6 system. There may be an easier solution... I don't know for sure. So, my apologies in advance if this is the "long way."
