reduced feature set.

libpayload's PDCurses port provides a full features curses
implementation, including libpanel, libmenu and libform (which
are taken from ncurses).

The alternate character set (ACS) is used for drawing lines and
displaying a couple of other special graphics characters. The
ACS characters generally look good on screen, but can be difficult

help
For recent chipsets with 256 NVRAM bytes, you have to access the
upper 128 bytes (128-255) using two different I/O ports,
usually 0x72/0x73.
On some chipsets this can be a different set of ports, though.
The VIA VT8237R for example only recognizes the ports 0x74/0x75
for accessing the high 128 NVRAM bytes (as seems to be the case for
multiple VIA chipsets).
If you want to read or write CMOS bytes on computers with one of
these chipsets, say 'y' here.
