Message-ID: <1990Feb11.191736.7917@agate.berkeley.edu> Date: 11 Feb 90 19:17:36 GMT References: <5420@bgsuvax.UUCP> Sender: usenet@agate.berkeley.edu (USENET Administrator;;;;ZU44) Organization: University of California, Berkeley Lines: 14 How many of the 386/AT motherboards out there are able to assign the top 384K of the first 1M as exTENded memory? This question was discussed a while ago in this news group, but I don't remember seeing a definite answer. I know the DTK/386 20Mhz motherboard (with a DTK BIOS) can do it. However, I haven't seen any other motherboards used by low-end clone makers that claim this capability. If you believe the sales people in the stores I went, once you disable the ROM shadowing in their machines those memory locations (the top 384K) are lost. Why is the DTK machine different? Motherboard, BIOS, memory configuration?
