Welcome to MkLinux Developer Release 3 (DR3) FTP archive.
If you're not familiar with MkLinux, please see the web site:
http://www.mklinux.apple.com/
The easiest way to install MkLinux is using the MkLinux DR3 CD-ROM. Please
see the web page or the DR3 announcement for details on obtaining the CD.
In most cases, it is possible to install MkLinux DR3 from this FTP archive.
If that's what you want to do, continue reading!
We've duplicated the CD's directory structure in this FTP archive. However,
there are a few differences, which are outlined below.
What's on the CD
----------------
The DR3 CD contains the following files or folders at the top level:
README - Mac and Unix versions, containing identical text
MacOS Utilities/ - Three partitioning programs that run under MacOS
Mac Files/ - The pieces of MkLinux that reside in your MacOS volume
mach_servers/ - The pieces needed to boot the MkLinux installer
RedHat/... - Many packages that can be installed as part of DR3
SRPMS/ - Sources to the above DR3 packages
extra/... - More packages that can be installed later
mklinux_source/ - Sources to MkLinux's Mach microkernel and Linux server
misc_source/ - Other sources that may be of interest
What's different here
---------------------
There is an extensive README file on the CD, which has been renamed
"README_DR3" in this FTP archive. You should read it, as almost all of it is
applicable to you. The "README" that you're looking at right now describes
only the additional information that you need to install MkLinux from this FTP
archive.
The file "Announcement" contains the announcement for MkLinux DR3.
The folders "MacOS Utilities", "Mac Files", and "mach_servers" are recreated
here in two forms. Each folder has been bundled into a self-extracting
archive. If you are downloading these pieces for the first time, we suggest
that you simply retrieve the three "sea.hqx" files. If you're looking for just
one or two files from one of those folders, then you can look in the similarly
named directory here. (If you do this with files in "mach_servers", be sure
to FTP them in _binary_ mode, even "bootstrap.conf", even though it looks like
a text file!)
There are a few RPMs and SRPMs that are available here, in the "extra"
directory that do not exist on the CD. These files were left off the CD
because they were either too large to fit on the CD, or simply not required
for DR3. They are:
extra/RPMS/howto-translations-5.0-5a.noarch.rpm
extra/SRPMS/howto-5.0-5a.src.rpm
extra/SRPMS/X11R6.3-01-1r.src.rpm
extra/RPMS/emacs-19.34-1B.ppc.rpm
extra/RPMS/emacs-X11-19.34-1B.ppc.rpm
extra/RPMS/emacs-el-19.34-1B.ppc.rpm
extra/RPMS/emacs-nox-19.34-1B.ppc.rpm
extra/SRPMS/emacs-19.34-1B.src.rpm
extra/RPMS/gcc-2.8.0-1c.ppc.rpm
extra/SRPMS/gcc-2.8.0-1c.src.rpm
The howto-translations and the howto SRPM are huge, as is the X SRPM.
They were left off the CD so that everything else would fit.
The emacs-19.34 is a slightly older version than the official DR3 version
(emacs-20.2). We've left it on the FTP site in "extra" because there are
a few things that don't work right in the newer emacs. Some zealous
emacs users will want to stick with the older 19.34 version for now.
EGCS (Experimental GNU Complier System) is the official compiler for DR3.
These days, most of the Open Source PowerPC compiler development is
occuring on the "egcs" package. gcc-2.8, which has some problems, is
provided via FTP only.
Installing DR3 using files from the FTP archive
-----------------------------------------------
1) Read the file "README_DR3" in this directory.
2) Use the programs in MacOS_Utilities to partition your disk for MkLinux.
If you don't know how to do this, go back to step 1.
3) Put the "Mac Files" into your MacOS system volume according to the
instructions in README_DR3. For now, ignore the part about SCSI vs. ATAPI
CD-ROM drives and editing lilo.conf's rootdev line. Yes, you will need to
edit the rootdev line; we'll get to that later.
4) Place the "mach_servers" folder at the top level (ie. not on the desktop)
of a suitable volume on your Mac. For MkLinux to be able to access your
mach_servers folder, the volume containing it must be:
a) on an HFS (MacOS Standard) volume, not HFS+ (MacOS Extended)
b) on a drive that MkLinux can recognize. Right now, MkLinux does not
recognize any drives attached to PCI SCSI adapters. Also, the DR3
kernel is known to have some difficulty with some IDE drives. If you
get the infamous "bootstrap cannot find config file" message, then
you may need to use a SCSI device to hold your mach_servers folder.
Once you completed the MkLinux installation, you will not need this
mach_servers folder anymore.
5) Determine the MkLinux device name for the partition where you finally ended
up putting your mach_servers folder. Typical device names look something
like this:
/dev/hda4 (fourth partition on the first IDE drive)
/dev/sda5 (fifth partition on the first SCSI drive)
/dev/sdb7 (seventh partition on the second SCSI drive)
The pdisk utility is probably the best tool to determine the device names
for your MacOS partitions. Use the "L" command to display the partition
tables for every drive attached to your Mac. It may take some sleuthing,
but you should be able to figure out the partition which contains the
HFS volume containing the mach_servers folder. Here's an example of pdisk
output:
Partition map (with 512 byte blocks) on '/dev/sda'
#: type name length base ( size )
1: Apple_partition_map Apple 63 @ 1
2: Apple_Driver43*Macintosh 54 @ 64
3: Apple_Driver43*Macintosh 74 @ 118
4: Apple_Patches Patch Partition 512 @ 192
5: Apple_HFS untitled 614400 @ 704 (300.0M)
6: Apple_UNIX_SVR2 swap 196608 @ 615104 ( 96.0M)
7: Apple_UNIX_SVR2 root 3381703 @ 811712 ( 1.6G)
In this case, the device name for the MacOS partition is '/dev/sda5'.
6) Put that device name into your lilo.conf file's rootdev line. You do this
by invoking the MkLinux control panel. Click on the "Custom" button.
SimpleText will launch and you'll be editing a preferences file called
"lilo.conf". Edit the "rootdev=" line so that it points to the partition
containing your mach_servers.
7) Reboot, when the MkLinux "Splash Screen" comes up, select MkLinux. After
a few moments of booting messages, you should be in the MkLinux Installer.
8) In general, you will follow the installer screens according to the
instructions given in README_DR3. However, once you get to Installation
Method, you'll need to pick something other than "Local CDROM".
The installer needs to be able to access the RPMs and other files that are
in the "RedHat" directory (under DR3 on this FTP site). If you are
connected to the internet via the ethernet port on your Mac, you can
retrieve the RPM's via FTP as they are needed (ie. you don't need to
download them all beforehand).
If you choose the FTP install, you'll need to know the name of an FTP
site and the name of the directory that contains the RedHat directory.
On ftp.mklinux.apple.com, that directory would be "/pub/DR3", because
that's where the RedHat directory is.
Another thing you need to know is that sometimes the installer cannot
determine the address of the FTP site if its name is a "DNS alias".
For instance, the installer won't recognize "ftp.mklinux.apple.com"
because that's really an alias for "www.mklinux.apple.com". As a last
resort, you could always use the actual IP address (ww.xx.yy.zz) of the
ftp site.
And one more tidbit about FTP installs: the main MkLinux FTP site,
ftp.mklinux.apple.com (or really, www.mklinux.apple.com) is usually under
heavy load. If you try to do a FTP install directly from it, the install
process may fail and you'll have to start over. You'll be much better off
if you choose a Mirror site. The Mirror site list is shown when you
connect to ftp.mklinux.apple.com, and is also contained in the file
"Mirrors" at the top level (/pub) of the FTP archive.
As an alternative to the FTP install, you can load all the RPMs onto a
local disk. The structure of the RedHat directory must be preserved,
including the directory (or Folder) "RedHat" itself. Some of the files
in the RedHat folder have names longer than 32 characters, and their names
will be truncated when placed onto a MacOS volume. Don't worry about this;
the installer knows that if the files are coming from a local disk, it may
have to look for truncated names.
9) Continue in the installer according to README_DR3.
When you have completed the installation, you may remove the "mach_servers"
folder.

MkLinux device naming primer:
Here's how drives are named under MkLinux, for any release since Nov 26, 1997,
including many of the "wips" on the ftp site, as well this pre-DR3, DR3 final,
and all versions going forward.
SCSI Drives:
MkLinux scans your SCSI busses counting from ID#0 through ID#6. It scans
the internal bus first, then the "internal/external" bus. Any disks that
are found are assigned the names "sda", "sdb", "sdc", REGARDLESS of their
SCSI ID. So, if you don't have a drive at ID#0, but you do have one at
ID#1 on the internal bus, then that drive will be "/dev/sda". This is
different from earlier MkLinuxes. SCSI CDROMs are also labeled as they
are found in the scan, starting with "scd0". So, here's a gnarly example:
Internal
ID What type disks cdroms
0 (empty)
1 SCSI Disk Hard Disk /dev/sda
2 (empty)
3 cdrom CDROM /dev/scd0
4 zip drive Hard Disk /dev/sdb
5 SCSI Disk Hard Disk /dev/sdc
6 (empty)
External:
0 (empty)
1 (empty)
2 SCSI Disk Hard Disk /dev/sdd
3 (empty)
4 Another CDROM CDROM /dev/scd1
5 jaz drive Hard Disk /dev/sde
6 (empty)
^ ^

consecutively in these two --------+----------------+
columns?
ATA and ATAPI drives:
ATA naming is quite different from SCSI naming.
Your IDE drives and ATAPI CDROMs are numbered like so:
On the first ATA bus, you have /dev/hda and /dev/hdb. On the second ATA
bus, you have /dev/hdc and /dev/hdd. Etc.
Example:
On the PowerMac 4400, the first ATA bus has the hard disk, and the second
ATA bus has the CDROM:
First ATA bus:
Master IDE Drive /dev/hda
Slave (empty) /dev/hdb
Second ATA bus:
Master CDROM /dev/hdc
Slave (empty) /dev/hdd
^

+ These names fixed to the assigned positions
even if there's an "empty" position.
Partitions:
Once you have determined what MkLinux calls the drive, the partition number
on that drive is specified by appending a number.
Examples:
/dev/hda5 (partition #5 on hda)
/dev/sdd4 (partition #4 on sdd)
The best way I know to look at a partition map is to use the pdisk utility.
It's not pretty to look at, but it really tells you what's going on with the
drives in your system. Pdisk is in the "MacOS_Utilities" directory on
this ftp site.
