Revisiting the PC-D driver as I got hold of a collection of disks: If you install a harddisk from scratch using an original bootdisk, there are two mandatory reboots: One after the low level format using HDINIT, another after creating a partition in FDISK.

Both times, the reboot ends in MAME only showing a cursor in the left top corner (same after a reboot using F3), a Shift-F3 reboot is needed to proceed.

I don't remember this behaviour after the driver was becoming functional, so maybe it's a regression.
