FULL CD

So you may have downloaded fullcd.iso.gz and burned it into a CD. Now you actually want to use it.

1. Boot the CD
2. It takes a few seconds (5 or so) to load the loader then a few more to load the kernel and start the system up
3. Eventually it gets to the message press control-shift-L to logon
4. So press control-shift-L and it will put you in the shell (the startup file is set up to bypass username/password prompt)

• A dir command will list out the directory on the CD
• A help command will list out other commands you have
• The edt command will start the edt editor
• Make a bootable hard drive:

  ide_pm represents the master drive on the primary idecontroller. oz_dfs is the name of the template device for the filesystem driver. Thus ide_pm by itself references the raw hard drive, whereas ide_pm.oz_dfs references the filesystem of the hard drive.

  If you want to put it in a partition on the hard drive, use fdisk under Linux to set the partition type to 0x69. Then when OZONE boots, use stuff like ide_pm.3, this refers to partition 3 (numbered 1 thru 4) on the primary master ide drive.So ide_pm.3.oz_dfs would refer to the filesystem on partition 3 of the primary master ide drive. You would have to have something like lilo set up to boot from partition 3.

  So how do I know what disk devices this stOOpid thing thinks I have? Not too tuff, try a show system -devices command. Look for things with alias names beginning with _disk, those are your disks. For example, the CDROM should be in there as something like ide_ps.1 (ide primary slave, scsi device id 1). A partitioned drive will be in there as both the whole drive (eg, ide_pm) and the partitions (eg, ide_pm.3).

  1. init ide_pm.3 oz_dfs hardisk - format the filesystem on the hard drive partition 3
  2. mount ide_pm.3 oz_dfs - mount filesystem of partition 3
  3. copy /ozone~ ide_pm.3.oz_dfs:/ozone - copy the ozone system directory tree
  4. copy /bin~ ide_pm.3.oz_dfs:/bin - copy the bin86 and binutils directory trees
  5. copy /g~ ide_pm.3.oz_dfs:/g - copy the gcc and glibc directory trees
  6. if you want the SMP kernel, do
     1. set default ide_pm.3.oz_dfs:/ozone/binaries/
     2. rename -newversion oz_kernel_smp.elf oz_kernel.elf
  7. write boot block (enter it all on one line):

     run oz_util_writeboot.elf	-set load_device ide_pm.3 -set load_fstemplate oz_dfs -set load_script ../startup/null.ldr -set startup_input ../startup/hardiskstartup.cli ide_pm.3.oz_dfs:/ozone/binaries/oz_loader_486.bb

  8. dir ide_pm.3.oz_dfs:/~ - see what's on the hard drive now (~ is recursive search)
  9. shutdown -reboot - don't forget to remove CD from drive before it actually reboots
• If you enabled the SMP kernel and it won't boot, you can undo it by rebooting the CDROM and renaming the SMP kernel file back:
  1. set default ide_pm.3.oz_dfs:/ozone/binaries/
  2. rename oz_kernel.elf; oz_kernel_smp.elf;
  The semi-colons on the filenames of the rename command tell it to only rename the latest version of the file. The uniprocessor kernel is still there as oz_kernel.elf;1.
• The username is root and the password is tree. You can change the password with the change password command.

Compiling a program

Now that you have everything on the hard drive, suppose you want to create and compile a C program.

1. Create a directory for your source files, like /mystuff/
   credir /mystuff/
2. Set the default directory to it
   set default /mystuff/
3. Put your source files in there. Either create them with edt, copy them from a floppy or use the FTP daemon to get them.
4. Compile a source file into an object file (all on one line)
   gcc -O2 -DOZ_HW_TYPE_486 -c -o file.o file.c
   You can use whatever options you want with gcc, but you must include -DOZ_HW_TYPE_486
5. Repeat the above step for each source file
6. Link to create executable (all on one line)
   ldelf exefile.elf file1.o file2.o ... /ozone/objects/oz_crtl_start.o /ozone/libraries/oz_crtl.a /ozone/binaries/oz_kernel.elf
7. Run the resulting image
   run exefile.elf command line arguments

Transferring files to/from a FAT floppy (or hard drive partition)

Suppose you want to copy something to/from a FAT floppy.

1. Load the FAT filesystem driver
   run oz_util_kimage.elf load oz_dev_fat.elf
2. Maybe initialize floppy
   init floppy.p0 oz_fat somelabel
3. Mount floppy
   mount [-readonly] floppy.p0 oz_fat
4. Copy some files to it
   copy /ozone/startup/*.cli floppy.p0.oz_fat:/
5. List them out
   dir floppy.p0.oz_fat:/
6. All done with it
   dism floppy.p0.oz_fat

Internet access

If you have a Dec Tulip card with a 21041 or 21140 in it, you can start the ip stack. It also works with a Realtek 8139. The tulip driver only supports twisted-pair 10MHz mode whereas the Realtek 8139 driver will autosense for either 10MHz or 100MHz, and half- or full-duplex (ie, the chip pretty much did it without any effort ;). Edit the /ozone/startup/ip_startup.cli file:

1. Change the ip filter commands to your liking (or delete them all to let everything through)
2. Change the dectulip_2_4 to your device name (do show system -devices to see your device's name)
3. Change the 192.168... stuff to your IP addresses
4. Change the DNS addresses to your DNS servers
5. Exit editor and do a shutdown -reboot

Sorry I only have an FTP daemon, no client. There is both a telnet client and daemon.

Making kernel changes

To make changes to the kernel:

1. set default /ozone/sources/
2. Make changes to desired files
3. script ozmake_486.cli ../binaries/oz_kernel.elf
4. shutdown -reboot

1. press return within 5 seconds before the first loader prompt times out
2. dir ide_pm.3.oz_dfs:/ozone/binaries/ - to see what's there
3. delete ide_pm.3.oz_dfs:/ozone/binaries/oz_kernel.elf; - to delete the latest version
4. dism ide_pm.3.oz_dfs - to dismount disk before booting kernel
5. press control-Z to resume booting
