3Luna-88K do not require any specific preparation prior to the OpenBSD
4installation. However, you might want to get familiar with the PROM
5interface, in order to be able to boot the installation media and, later,
6specify the correct boot parameters.
7
8The first set of DIP switches in the front panel (DIP SW1) is used to
9select the machine behaviour upon powerup, as well as the preferred
10console device.
11
12The meaning of these switches will depend upon your particular machine.
13On the Luna-88k, the 'down' position is 'on', and the 'up' position is
14'off', while the Luna-88k2 uses the opposite convention (i.e. 'up' is 'on'
15and 'down' is 'off').
16
17If the leftmost switch in SW1, #1, is in the 'off' position, the system will
18auto-boot from the boot device saved in NVRAM. Otherwise, the boot process
19will stop at the PROM prompt.
20
21The second switch in SW1, #2, selects the console device. When in the 'on'
22position, it selects the serial console port as the console; otherwise,
23the graphics display and keyboard are used as the console.
24
25While the Luna-88K2 uses ``standard'' serial ports, the earlier Luna-88K
26have a specific connector. Wiring information for this connector can be
27found at the following URL:
