Misc installation notes for installing the powerpc port.

Probably will change greatly or be moved eventually.

+are to be booted from.

+the boot from the floppy.
+ok boot ofdisk0:\boot.ppc 
+
+Before installing on the harddrive, first a DOS partition needs
+to be created.
+fat-partition hdiskX 1 
+This will create a 1 MB dos partition. This is necessary to
+boot, The boot loader will be copied here later.
+
+Now boot off of the boot (kc) floppy.
+ok boot ofdisk0:\boot.ppc -a
+Boot: ofdisk0:/bsd -s
+
+Note: it is necessary to use the -a option and specify
+ofdisk0 (devaliased above) to correctly mount the floppy
+root disk.  Also the floppies are in ISO9660 format, so
+it is not possible to mount them read/write, MFS or the like will
+eventually be nessary.
+
+
+At the prompt to insert the filesystem disk, 
+--
+Please insert root disk and press ENTER 
+--
+put in the disk with the inst-20.fs image in the floppy.
+
+
+Using fdisk, create a disk partition of type 0xa6. (0xa6 may change)
+fdisk -u <drive>.
+Do not use the -i option, we do not want to replace the bootblock
+that openfirmware has put down, just modify the parition information.
+
+the "fat-parition 1 hdiskX" from before will have created a
+parition similar to this:
+--
+MBR Partition 0: sysid 6=0x06 (Primary 'big' DOS (> 32MB))
+    start 1, size 2048 (1 MB), flag 0x80
+    beg: cylinder    0, head   0, sector  0
+    end: cylinder    0, head   0, sector  0
+--
+
+Make certain to leave that unmodified and as the active partition.
+That parition is currently used to hold the boot loader.
+
+I changed the labeling to have non 1 for heads and sectors/track.
+I am not certian if that is correct or wise.
+
+Modify one of the paritions (Use 3 for example)
+Create a partition with:
+sysid [166]
+start [2048*] "Should use sectors/cyl * n to get just greater than 2048."
+size  [disk size - start]
+
+when the label is written back out to the disk these messages are normal:
+--
+fdisk: DIOCWLABEL: Inappropriate ioctl for device
+fdisk: DIOCWLABEL: Inappropriate ioctl for device
+--
+
+Now it is necessary to create a UNIX disklabel for the drive
+(Would be nice if /etc/disktab had some ready)
+
+The easiest way to do this currently is to take the output of
+disklabel sdX
+and cut and paste it on another machine to edit it into the desired
+disklabel.
+
+Then using a trick I found, cut and past the edited label back into
+the other machine after running the command
+disklabel -R sdX /dev/tty
+NEVER use the "-r" option 
+Also make certain to check the label just written
+with "disklabel sdX"
+
+Note: only paste a few lines of the disklabel into the console
+at a time, Otherwise the input buffer can overflow and lose characters.
+
+Make certain to keep the partition 'd' around. The only
+change to possibly make to it would be make it's type MSDOS?
+
+It probably would be nice to eventually make the install kernel
+have option MFS or the rd device, so that "disklabel -e" could be used.
+
+
+Now newfs the newly created FFS partitions.
+Do not newfs the parition d (size 2048)
+
+mount /dev/sdXa /mnt
+mkdir /mnt/usr
+mount /dev/sdXg /mnt/usr
+
+(network installtion, CDrom or other do as necessary)

+ifconfig ofnet0        inet XXX.XXX.XXX.XXX netmask XXX.XXX.XXX.XXX

+mount /dev/sdXh /tmp
+cd /tmp
