Alternatively, you might flip a standard plcc-32 socket over the mainboard-chip. then wire a secondary plcc-32 socket to it wired 1:1 - except you connect /reset and /oe on the replacment chip, while you route the /oe from the mainboard to an NC pin on the secondary chip.

badly in need:
- is it practical to upgrade the secondary pad with an 2 MBit flash part ?
2 MByte: the southbridge needs to decode the full 2Mbyte (these are 16Mbit parts) address range for it to be useful in practice. A lot of the SB parts I looked at, years ago, reserved the top 2M of the 2 GB space. so it is something we have to check.
