I think this will be interesting for USB / UDMA / ... driver
users and developers as well :-) The new version improves the
compatibility and speed. New PC speaker support infrastructure
and faster CPU, debugger shows virtual device states, added a
virtual i82540EM Gigabit-LAN chip (port from Qemu) and so on.
VGA improved, for example blinking and retrace emulation, with
some ideas from DOSBox. "Improved PCI boot ROM support"...
Happy testing :-)
