[9fans] PowerPC, usb, modem, etc.

[D. Brownlee]

Recently, there was a post about new PowerPC ports.
What's coming? Any for Apple hardware? If not, I may
look into it, because there appears to be enough low-level
software in NetBSD's 'macppc' port to make things easier.
I have an ancient iMac here, too s-l-o-w for OS X, but
runs NetBSD, diskless, alright.

So, I have a USB modem. I need to read about usb support
for Plan 9; I would like to use the usb modem with Plan 9
running on the i386 box. First I'll try running u9fs on
the iMac to see whether it can serve the modem. Any
suggestions/comments would be helpful.

By the way, on the Plan 9 i386 box I:

	ftpfs iMac
	cd /n/ftp
	cd somewhere #where there are alot of big ones like plan9.iso
	file *

This creates alot of activity (gives 'stats' something to
do, anyway), and it is interesting that the numbers in the stats
window are, in decreasing order:

	intr, syscall, context, ether

Is that meaningful?
Despite all that activity, I can still render PostScript quickly
in another window:

	man -t plan9.ini | page -w

Concerning plan9.ini: I want to experiment with my vga settings,
but if I get them wrong, the monitor just displays something
like "hsync out of range." Is there any way that I can drop
into terminal mode at that point in order to edit plan9.ini
and reboot. Will ^t^tr halt the filesystem? If there is no
way to get a terminal prompt, I could boot another OS and
edit plan9.ini from there.

you actually have rio running on the system, but you just can't see it.

there are several things you can do:

	- ssh to the system (if it's a cpu server at least)
	- get a serial console running
	- cpu to the system from a remote machine

i used to (pretty sure other people did too) just start X on the same
monitor and get the hsync/vsync values from xvidtune. once set i've never
had to change them.

i see now that one of those still remains in /lib/vgadb --

	# from aam396@mail.usask.ca

Thanks. I'll try xvidtune.

Aha! vnc could work, too.
