> SYSTEM 17,344 (17K) 10,992 (11K) 6,352 (6K) > HIMEM 2,704 (3K) 2,704 (3K) 0 (0K) > COMMAND 3,648 (4K) 3,024 (3K) 624 (1K) ... > LBACACHE 20,432 (20K) 0 (0K) 20,432 (20K) ... > Conventional 611K 17K 594K > Upper 152K 87K 65K That is a very small "total RAM" (611k) Either you load some driver before DOS (e.g. LBA helper for big HDD on old BIOS) or you have a virus loaded before DOS or you have a driver or virus inside DOS which allocates RAM by reducing the "total". > Same HDD, different MB: > SYSTEM 17,328 (17K) 10,992 (11K) 6,336 (6K) > HIMEM 2,704 (3K) 2,704 (3K) 0 (0K) > LBACACHE 20,464 (20K) 336 (0K) 20,128 (20K) > COMMAND 4,064 (4K) 3,024 (3K) 1,040 (1K) ... In this version, LBACACHE uses TUNS, but the stack is small. I assume this is not the current version of LBACACHE yet ;-) > Conventional 639K 37K 602K > Upper 88K 87K 1K Note that this other (newer) mainboard leaves less space for DOS upper memory. On the other hand, 639k total is a very normal value: It typically means 640k minus 1k for extra BIOS data area. Extra as opposed to 40:xx (0.25k).
