I have a Sony Vaio VGN-SZ4XWN/C which has the original 120 GB hard disk.
I've partitioned that as Vista and Solaris x86 but I've had enough of
Vista, so are going to partition it with Solaris x86 and XP - drivers
are available for most/all the parts.

I've purchased a larger (300 GB disk), but don't know exactly what needs
to be undone to get at the disk. Can anyone tell me? What I thought was
the access panel turned out to be for memory.

Is there a service manual anywhere? I'm used to Sun workstations, where
Sun make available very good service manuals. Somehow I suspect this is
not the case with Sony.
