Scratch that - it should boot IF the CDR is the 'zeroth' device.

Mine is not, and I am too tired to open the case and mess with it.

BTW - 9 renders very cleanly on the Lenovo at a manually-entered 1280x800x16
using the onboard Wintel 945GM/GMS/GME graphics controller, ergo I presume  9 is
in VESA mode.

The Unichrome has always been comfortable with VESA under other OS'en that don't
have a bespoke S3 driver handy, so unless you are looking for a bespoke,
accelerated driver....
