+Prepare image on usb-storage:
+ 1. the easiest way:
+	$ dd if=ppcrcd.iso of=/dev/sda
+    but you will not be able to put anything else on such device
+
+ 2. prepare mac-partitions, like this:
+	/dev/sda1 Apple_partition_map Apple     63 @ 1   ( 31.5k) Partition map
+	/dev/sda2         Apple_HFS PPCRCD  122880 @ 64  ( 60.0M) HFS
+	/dev/sda3 Apple_UNIX_SVR2 Data   880576 @ 122944 (430.0M) Linux native
+
+    format as HFS
+	$ hformat -l PPCRCD /dev/sda2
+
+    mount destination and copy all files from CD image:
+	$ sudo mount -t hfs /dev/sda2 mnt
+	$ sudo cp -a /path/to/cd/* mnt/
+	$ sudo umount mnt
+
+    set chrp-script atribute:
+	$ hmount /dev/sda2
+	$ hattrib -b :ppc
+	$ hcd ppc
+	$ hattrib -t tbxi -c TBXI bootinfo.txt
+	$ humount
+
+    this way you have rest of disk for use under linux
+
+
+
+Now, how to boot:
+
+1. connect usb-disk and reboot 
+
+2. press Command-Option-O-F (Apple-Alt-O-F) to enter open firmware
+
+3. look for usb* aliases:
+	0 > devalias
+
+4. check for one with usb-disk:
+	0 > dev usb0 ls
+	 ok
+	0 > dev usb1 ls
+	ff9dc2c0: /disk at 1
+	 ok
+	0 > dev usb2 ls
+	 ok
+
+5. boot script:
+	0 > boot usb1/disk at 1:2,\\:tbxi
+
+    where:
+	"usb1/disk at 1" is device path
+	"2" is partition where PPCRCD files are
+	"\\:tbxi" is chrp-script file
+
