Unhappy What live distros are there for a mac g4 and why do all my attempts to DL chunk?


Hello Linux fans! i as you can probably tell am a newbie. my freind introduced me to linux and i am loving it. i use slackware 10.0 but my question today is in refrence to mac g4's. i wanted to try out a live distro for it but i am unable to find one that works. i got knoppix ppc and the system still boots up to the mac os x. not that i dont like it but linux is somewhat my OS of choice. i would really like to use it on the mac. i also tried to DL a full distro of yellowdog and that failed. it seems i have alot of trouble DL any full distro form fedora core 3 to mandrake to debian none of them worked. has anyone had similar issues with the DL and can someone refer me to a live distro out there for a mac g4. thanks for your time and concern.

You say that you try to boot the Knoppix CD and mac osx still boots anyway. Have you got the machine set to boot from CDROM? I don't know how your BIOS is on that G4 but you'll need to select booting from CD before hard drive to get the live CD or any other CD to boot.

Try Ubuntu, that may work. But before that make sure that you have your correct BIOS setting for booting it from CDROM.

hello guys thanks for the reply

sorry about not being detailed on the g4. i tried to set it through the system prefrences but it would only allow me to select either HD or network but not cd. i am the system admin and the only two options shown are the HD and network. also i tried to drag and drop knoppix into the boot panel but of course that did not work either. ya'll mentioned bios. how do i access the bios on the mac. is it the same as an x84 system. esc and then f1 or is it different. this is my first mac so i am kind of ignorant in regards to its operation. about unbuntu i tried to DL it but it keeps failing. i have no clue why. it will get about 30% and then chunks. i burned the iso the way it should for knoppix but i guess i have to get to the bios before i can say for sure that it will not work. how can i get into the mac bios to change that setting and how will i approach the chage once i am there. i guess i need a step by step since i am completely new to the mac system. about linux any known working mirrors would be greatly appreciated. since everyone that i go to seems to chunk my DL.lol. thanks for your replies guys any more info again would be greatly appreciated. thank you both.

http://linuxiso.org/
Large downloads sometimes stall for lots of reasons. Like web site timeout, or network problems, or OS stall ect. I suggest that you use a download manager like "wget" that will resume and keep trying until it gets the file. For Linux "wget is just outstanding. There are others for winblows ect. Downloads from the distros FTP site will often times be the fastest. If there are many users getting the file at once your dl time will increase. If you are on a Linux box just open konsole or xterm ect, and
wget http://www.sitename/ect/etc/linuxdistro123.iso
turn the monitor off and go to sleep, in the morning you will have the file or wget will still be trying. Read the man page for wget.

Sorry, I don't know Macs.

thanks teckk

i just wante dtow rite thank you for your advise teckk. i have been trying linuxiso.org but i never thought about using the DL manager. all i have at my disposal at the moment is winblows so i will just have to deal with tha for now. i have flashget on the laptop i am using but i will try with that instead of just letting it go. hopefully this will work and i will have slackware 10.1 running on this laptop and next i will try to conquer the world. HAHAHAHA!!! j/k as for my mac i will wait to see if anyone has some possible solutions. thanks again teckk.

CD boot on Mac

To force a boot from the optical drive on a mac hold down the "c" key durring boot.

To enter the OpenFirmware command line interface hold down "command-control-o-f" Note: some older machines with ATI video MAY display a blank screen, requiring a terminal session to access OF, some VERY new machines may have a password set, I don't know what it is.

I tried Ubuntu Live CD on the 12 in G4 PowerBook worked great!
I had to hold down the key "c" for couple minutes for it to start from the CD.

typo in my last post

glad you got it to work...

"c" is correct for boot from optical drive, but it's "command(apple)-OPTION-o-f" to get to the openfirmware CLI. The rest of what I said is ture. Some "old-world" power macs with ATI video and a APPL-ROM (as opposed to ROM-in-RAM that new machines use) may not initialize the display when booted into openfirmware. The default interface for these is through a direct-terminal connection to the modem port (not the printer port). Video can be initialized from the serial port interface, or you can try a blind initialziation. Do a google search for the strings needed. They are different depending on the graphics chip used.

Also I've heard that on machines that have password protected OF, resetting the NVRAM (called P-RAM in Macs) three times in a row will clear the password, But I've never tried it. To clear the P-RAM, hold down "command-option-p-r" during boot untill the start chime plays again. Three consecutive clears will require holding the key combo until four chimes have been heard.

There's lots of info available on the Web for OF commands, but some usefull ones are "boot/dev/...." where "dev" is the name of the drive and the path follows. almost any device detected by OF can be booted from, even from deeply nesested folders, as long as the path points to a valid boot file ("mklinux.c" for example). just "boot" uses the default boot device, usually "APPL-ROM" or "hda0/system folder("system" on OS-X)/etc/etc..." "words" is another good one to know, it'll list the commands supported by the version of OF the machine is running. OF uses standard *nix device names, except for the APPL custom chips. (example: hda0 is IDE/ATAPI MASTER (Bus 1) Partition 1(0). and sdb3 is SCSI drive 2, (Bus 1), partition 3.) for machines with two IDE buses hdc* and hdd* are bus 2 Master and Slave respectively. But if you didn't already know this maybe you shouldn't be fiddling with OF .

Openfirmware is much more complex and MUCH MUCH more powerfull than IBM-PC style BIOS and care should be taken when fiddling with it. Unwise use of OF could do silly things like TURN OFF THE CPU IN PRAM (requireing a replacement ROM), or ALTER THE MEMORY AND PCI CONTROLLER ADDRESSES. Be carefull folks, but have fun!
