- [ DOS ] QCACHE V5.0 update - QCACHE now reserves "high" XMS memory, to allow more memory below 16-MB for old Novell 24-bit software. Thanks to Erwin Veermans for this idea. Fixed an ERROR in QCACHE for /N or if no UltraDMA disks are found! No changes to QDBOOT. SATA-only users should upgrade to V5.0 QCACHE immediately!
