AT /370 Adapter Installation Requirements
Before you install the AT /370 adapter, you must have
an IBM Personal Computer AT with 512K bytes of
memory on its system board.
The memory card part of the AT/370 adapter also has
512K bytes of memory, 128K bytes of which are
directly addressable by the Personal Computer AT
when the AT/370 option is not in use. Because the
AT/370 adapter takes the place of the 128KB memory
expansion adapter, base memory size includes the
512K bytes of memory on the system board and the
128K bytes of memory in the AT/370 adapter.
Base Memory size MUST be set to 640K bytes during
setup:
•
Go to the "SETUP INFORMATION" foldout in
the back of the IBM Installation and
Setup-Personal Computer ATmanual
•
Circle "640K bytes" under "Total base memory
size"
•
THEN RETURN TO THIS MANUAL to complete
installation of the AT/370 option.
Tool Requirements
•
Medium-size, flat-blade screwdriver
Optional:
Medium screwstarter
3/16-inch nutdriver
1I4-inch nutdriver.
