DOS 5.0>>AST RAMpage card

[JOHN WAGER]

I doubt if anybody will reply that they have used REX.SYS or other
software to change EMS to extended memory for loading DOS5 "high."
I have used AST boards, and the way DOS uses the "HMA" directly
would be VERY difficult to duplicate by software calls, besides which
it would be much slower and less 'stable.' I think the only option
is to throw the dip switches to set aside 64K for extended.
