I have an old Pentium II, with a 3GB drive and 256MB RAM, Running Win98...I have a new app that won't allow install without Win2K...I have only 700MB free space on my drive. How much space will a seperate Win2K OS installation take up?. And can I install it a seperate directory in the 700MB space, use dual boot option, and boot to the new OS only to run my one application? ----Secondly, if the answer is No Way,.. I have a second hard drive i could install but only one connection on the IDE cable. Can I get an IDE cable with two connections and slave the second drive through the same IDE port 1. (my second IDE slot is being used for my CD burner). I would then install Win2K on the second drive and still dual boot. I hope i have explained enough of my problem.
