Installing a coprocessor
Apricot supply three coprocessor add-ons for XEN-LS
machines:
* Intel 80387SX-16 for the XEN-LS 386SX-16
* Intel 80387SX-20 for the XEN-LS 386SX-20
* Intel 80487SX-20 for the XEN-LS 486SX-20
Note that your XEN-LS may have already been fitted with a
coprocessor either during manufacture or by your supplier.
Installation
Do not remove the coprocessor from its anti-static wrapping
until you are ready to install it. To install a coprocessor:
1.
Take suitable anti-static precautions as described in
the
XEN-LS Owner’s Handbook.
2.
Switch off the computer and disconnect it from the
AC power supply. Remove the system unit cover,
the expansion card cage and the bridge assembly
as described in the
XEN-LS Owner’s Handbook.
3.
Locate the coprocessor socket by referring to the
following illustration and/or the layout diagram inside
the system unit.
