I have a pc with 3 large harddrives. The first is partitioned into 4 primary partitions each containing an XP operating system.
The second 2 drives are partitioned into 2 local drives apiece. I am going to put the page file on one of the local drives, can all 4 operating systems share this page file?
Yes, but it's a bit of a fiddle. The partition the swap file is to exist on must be FAT32 (so no NTFS permissions stop the other OS's SYSTEM user from accessing it). The OS's need to have their swap file set to the same settings (location and minimum/maximum sizes).
