Intel Real Mode memory ends here. Memory beyond this point is
accessible only in Protected Mode. Only the Intel 80286 and
80386 currently have a Protected Mode. The 8086 and 8088 do
not have a Protected Mode, and therefore CANNOT access memory
beyond the 1 Megabyte barrier.

Note that the ROM BIOS has a duplicated address space which
causes it to "appear" both at the end of the 1 Megabyte Real
Mode space and at the end of the 16 Megabyte Protected Mode
space.
The addresses from:
0E0000 to 0FFFFF
are equal to
FE0000 to FFFFFF
This is necessary due to differences in the memory addressing
between Real and Protected Modes.
Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!
This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.
But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
