[net.micro.pc] XT ROM and Memory

D.psych36@Berkeley@ucscc.UUCP (07/17/83)

1) Can a PC operate correctly with the U33 ROM from an XT?

2) We have an XT with 192k on the mother board.  Instead of adding 64K
more chips to the mother, we put in a borrowed 64K board (with
switches 3,4 off).  For some strange reason, the XT counts up 320k of
memory (both in the power on test and diagnostic disk test).  Comment?

3) Is there any way of protecting the segment registers of the 8088 to
prevent users from crashing each other and the system?
