		+	''iBook modems''<br>
		+	iBook modems are not recognized by Ubuntu PPC releases since about 6.06. I found it to be true on the Dual Processor G4 tower that we worked on a short time ago, and if I remember correctly, other QS and MDD G4 models. I found a forum post from someone who found a workaround on a G3 iBook in Release 6.06. I'll try it on the iBook in work at the moment. From [http://ubuntuforums.org/showthread.php?t=355205 http://ubuntuforums.org/showthread.php?t=355205] :
		+
		+	I want to report a successful installation and usage of the iMac g3 600 internal modem. I have been helped by all the posts about iMac modems found here. I have the iMac modem
		+	working in 6.10 as this post shows.
		+
		+	Here is a quick summary:
		+	1) Ubuntu 6.06 is missing the pmac_zilog module.
		+	2) The autodect of the modem doesn't seem to work. You need to enter it manually.
		+	3) The sound is off when dailing.
		+
		+
		+	Here are things to check and do:
		+
		+	1) Check whether the modem driver is installed
		+	modprobe -l \| grep zilog
		+	/lib/modules/2.6.17-10-powerpc/kernel/drivers/serial/pmac_zilog.ko
		+	If you do not find it, you will need to load it. "All you have to do is add pmac_zilog to the /etc/modules file and after the next reboot your kernel will see it." Tommy
		+
		+	2) Find out the name of modem.
		+	dmesg >seedmesg
		+	gedit seedmesg
		+	and look for zilog. I found
		+	pmac_zilog: 0.6 (Benjamin Herrenschmidt <benh@kernel.crashing.org>)
		+
		+	[ 89.283552] pmac_zilog: i2c-modem detected, id: 1
		+
		+	[ 89.283620] ttyS0 at MMIO 0x80013020 (irq = 22) is a Z85c30 ESCC - Internal modem
		+
		+	[ 89.284227] ttyS1 at MMIO 0x80013000 (irq = 50) is a Z85c30 ESCC - Serial port
		+
		+	So, my modem port is /dev/ttyS0
		+
		+	3) Configure the modem. I used pppconfig. The automatic detecton of the modem didn't work. I used: /dev/ttyS0 and I saved the file to ppptest.
		+	cat /etc/ppp/peers/ppptest
		+	# This optionfile was generated by pppconfig 2.3.11.
		+

		+	hide-password
		+
		+	noauth
		+
		+	connect "/usr/sbin/chat -v -f /etc/chatscripts/ppptest"
		+
		+	debug

		+	/dev/ttyS0
		+
		+	115200
		+

		+	pon ppptest
		+
		+	pon return successfully. You will not hear the phone noise. For some reason the sound is turned off.

		+	''LTSP, Macs, Etch''<br>
		+	Vagrant got LTSP set up on the G3 B&W tower under Debian Etch. We tried to boot an iMac (500mhz/flwrpwr) as a thin client. The netboot process was EXTREMELY slow, taking 5 minutes or more. We watched the net traffic, and saw that the client was issuing DCHPINFORM several times during the very slow exchange. This use of DHCPINFORM is somewhat mystifying, since the spec (RFC 2131) says that DHCPINFORM is used by the client when an IP address has previously be externally assigned (I guess I don't know what that means). DHCPINFORM is a client request to the server to provide some parameter values, from what I can tell. I seem to recall from previous investigation that there can be a section in the DHCP configuration to provide parameter values. Maybe we should try to find out what parameters the client is asking for and provide them. This also seems to have a bearing on the slow netboot, because the client apparently waits for a DHCPACK (?) with the requested values, and times out after a while, proceeding to accept default values (again, my impaired iterpretation). Vagrant also said that he had spoken to someone who was running LTSP for Macs, and that the experience there was that client booting would be slow the first few times until some cache requirements were fulfilled. Not sure what that means, either.
		+
		+	Once the netboot succeeded, the client's Xserver failed to start, leaving a blank screen. I made some mods in the client's ''xorg.conf'' according to iMac FlowerPower needs, which had no effect. Subsequently I learned that X configuration is supposed to be controlled from ''lts.conf'' in the server. I wasn't quite clear on whether the location of ''lst.conf'' was local to the server or in the file system exported to the client.
		+
		+
		+	''iBook, Finnix, SystemRescueCD''<br>
		+	I burned a copy of the SystemRescueCD/PPC and tried that on the iBook. The boot process got pretty far along, but hung eventually.

 It turns out there are several other boot options and modifiers, which the Finnix web site calls ''Cheat Codes''.  The documentation is at [http://www.finnix.org/Cheat_Codes http://www.finnix.org/Cheat_Codes].  I'll give some of those a try.
