I've freshly installed MS-DOS 6.22 in a new VM under Parallels 13. Upon booting, HIMEM.SYS generates the error "HIMEM.SYS has detected unreliable XMS memory at address 00400002h. XMS Driver not installed." How can I correct this? I'd like to install Windows next, but Windows refuses to start because of the problem with HIMEM.SYS.
