<hr>Is it safe to delete $NTServicePackUninstall$ now that it has been installed? The other folders all have names like $NTUninstallQXXXXX$ with various characters.<hr>These folders contain backups of all the files replaced by a service pack or hotfix. Since you are planning to replace NT 4 with Windows XP, go ahead and delete them. You will lose, of course, any ability to uninstall them but it would seem a moot point.
<hr>delete the c:Client32 folder created when I installed my Novell client for Win NT?<hr>Most likely it's safe, since the NT client software most definitely will not work under XP - but again, do it at your own risk. You won't have Novell access until the XP installation is completed. And IMHO the XP client for Netware is just fine, I've yet to find a reason to install Novell's version.
<hr>NTFS drive size is limited to 2 gb for the active partition?<hr>I don't know where you got this number, but that sounds suspiciously like a limitation of FAT16, the only flavor of FAT that Windows NT supports. I have XP installed on a 10GB primary boot partition and never have I had a lick of trouble. Service Pack 4 and later allows NT to use drives in excess of 7.8/8GB providing the BIOS supports it.
<A target="_blank" HREF=http://www.win.tue.nl/~aeb/partitions/partition_types-2.html>This link</A> may be of interest - some of it is way out there and useless to all but the hard-core enthusiast <img src=/S/compute.gif border=0 alt=compute width=40 height=20> but there is enough information of use that I keep it bookmarked.
Hope that helps!!
