Yes, MEMR2.COM the memory test program from Lifeboat Associates uses
only the BIOS, overwrites CCP & BDOS.

You can get around the problem by reading in as much of the CCP & BDOS
as possible to the normal address where they're to execute, then
switch the load address to below CCP and read in the rest of BDOS up
to but not including the BIOS jump table.  Then move the code up to
where it belongs.  The address you use for this temporary area is not
critical - it could just as easily be 100h, 900h, 1000h or any
convenient area so long as you don't overwrite the CCP.
