A search on the 'net came up with Cypress (CYP) and IC Works (ICW), the
latter is now part of Cypress.  On Cypress's website, there is a W127-A
clock chip.

Unless this is a Hot-plug-capable box, that seems reasonable.  Hardware
should not have changed between power-up and reboot, so no need to re-check
all the slots again.

But maybe you can use this to your advantage.  Power up the system with a
card in the enabled extender board so that the box sees it and leaves the
clock enabled.
