Re: [parisc-linux] Serial MUX

[Christoph Plattner <christoph.plattner@gmx.at>]

Hello,

yes, I want to have E55 (and familiy) supported fully,
and I try to help in development (so far it is possible,
it is hard to get access to HP documentation).

To use the E55 (or family) as a diskless server, it works
(so you can reduce noise at the meantime, the disks cannot
be accessed in Linux - yet !).

For such a diskless operation, you need
	- serial console
	- ethernet
	- core system
All three things are running under Linux.
Again, you can use the PDC CONSOLE driver OR the MUX driver.
Both are accessed via ttyB0 at the moment.
