BINARIES

All the images require a Pent Pro or better with at least 32 Meg of memory.

*NEW* as of Mar 11, 2002: I have it running on a stRAaIGhT Pentium. At least one that CPUID's as type 052C and features mask 01BF. All I test for in the features mask is for 0019. I used to require 8019, but now I emulate the CMOV's if not present.

Here are some images for downloading that contain a bootable OZONE system:

• bootcd.iso.gz Bootable CD with just binaries (6.2 M) ** screenshots (from Bochs) **
• fullcd.iso.gz Bootable CD with sources and compiler stuff (30 M) (So what do I do with it?)
• hd40meg.img.gz Hard disk image for use with Bochs (6.2 M) ** screenshots (from Bochs) **

I also put together a simple floppy image. It uses the memory from 24M..32M for the system ramdisk. That leaves about 16 Meg left for applications.

Files (download either one):

• bootfloppy 1440Kb - exact image
• bootfloppy.gz 672Kb - image, compressed with gzip

Use:

1. Copy the bootfloppy image to a floppy (or gunzip bootfloppy.gz to a floppy)
2. Boot the floppy
3. It creates a ramdisk in memory range 24M..32M and puts the system files there
4. It then boots the kernel it loaded in the ramdisk
5. It takes a few seconds (5 or so) to load the kernel and start the system up
6. Eventually it gets to the message press control-shift-L to logon
7. It is safe to remove the floppy as the system is completely running from the ramdisk
8. 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 ramdisk
• A help command will list out other commands you have (not all executables for all the command are on the ramdisk, however, so you will get some file not found errors on some commands)
• The edt command will start the edt editor
• There is enough stuff there so you can copy the files to the hard drive if you want and set it up.

  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.

  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. credir ide_pm.3.oz_dfs:/ozone/ - create system file directory
  4. credir ide_pm.3.oz_dfs:/ozone/binaries/ - create system binary directory
  5. credir ide_pm.3.oz_dfs:/ozone/startup/ - create system startup directory
  6. -output ide_pm.3.oz_dfs:/ozone/startup/boothard.ldr cat null: - create null boothard.ldr file
  7. copy bootfloppy.cli ide_pm.3.oz_dfs:/ozone/startup/boothard.cli - copy the bootfloppy.cli to boothard.cli file
  8. copy e* ide_pm.3.oz_dfs:/ozone/binaries/e - copy the edt.elf file
  9. copy oz_c* ide_pm.3.oz_dfs:/ozone/binaries/oz_c - copy the oz_cli.elf file
  10. copy oz_k* ide_pm.3.oz_dfs:/ozone/binaries/oz_k - copy the oz_kernel_486.elf file
  11. copy oz_l* ide_pm.3.oz_dfs:/ozone/binaries/oz_l - copy the oz_loader_486.elf file
  12. copy oz_u* ide_pm.3.oz_dfs:/ozone/binaries/oz_u - copy all the oz_util_*.elf files
  13. write boot block (enter it all on one line):

      run oz_util_writeboot.elf	-set load_device ide_pm.3 -set load_directory /ozone/binaries/ -set load_script ../startup/boothard.ldr -set startup_input ../startup/boothard.cli -set memory_megabytes 0 ide_pm.3.oz_dfs:/ozone/binaries/oz_loader_486.bb

  14. dir ide_pm.3.oz_dfs:/~ - see what's on the hard drive now (~ is recursive search)
  15. dism ide_pm.3.oz_dfs - dismount hard drive
  16. shutdown -reboot - don't forget to remove floppy from drive first

The above works with a real system using a floppy and IDE hard drive. The Bochs I use has some patches I made and I sent in, and they adopted some of them. The only one they said they wouldn't do was to have the floppy drive accept a 'disable perpendicular' command as older floppy controllers choke on this command, so they wanted to trap it too. So I just removed it from my OS as it wasn't really necessary.

It still doesn't work with V1.3, though, as the Bochs floppy 'configure' command incorrectly expects 3 bytes for the command (total), instead of 4, so it prematurely indicates that it has received all command bytes before receiving the 4th. This is one I know they said they have fixed, but I haven't tested it with the most recent CVS stuff.

As of Bochs V2.0.2, stuff works as is. But if you try to use SMP, Bochs puques because it does not handle the local apic task priority register. There were also some small stuff that was messed up. So I modified it and now it works.

With Bochs V2.0.2, you will get a panic that says something like 'recal issued to non-hard disk' when OZONE probes for a CDROM. Just type in 'alwayscont' and Bochs will continue merrily on its way. I do a 'recalibrate' to probe for ATA drives and Bochs doesn't like it. I had to do the recal, it seemed at the time anyway, for an old hard drive I was using for testing.

Here are the repaired Bochs 2.0.2 source files:

• main.cpp
• cpu/apic.cpp
• cpu/cpu.h
• cpu/init.cpp
• iodev/floppy.cpp
• iodev/ioapic.h

I put together a patched bochs zip file with everything self-contained. I tested it with Windows XP and 2000. I don't have an WindoesNT system handy. The EDT keypad keys are scrambled using Bochs, though. Also, a little patience is required while the loader is gunzipping the files from the floppy onto the ramdisk.

1. Download it (2841Kb)
2. Unzip it into a folder (it all goes into one folder)
3. Run the bochs.exe by double clicking or starting from MS-DOS prompt
4. Select option 2, then supply filename rchd10meg.txt
5. Select option 5 and it should boot all the way through to the 'press control-shift-L to logon' message

If you want to enable password prompt for logging in, do this:

1. change the

         create logical name -kernel OZ_SYSTEM_TABLE%OZ_LOGON_IMAGE {load_dir}oz_cli.elf
   

   in boothard.cli to

         create logical name  -kernel OZ_SYSTEM_TABLE%OZ_PASSWORD_FILE {load_dir}../startup/password.dat
         create logical name  -kernel OZ_SYSTEM_TABLE%OZ_LOGON_IMAGE   {load_dir}oz_util_logon.elf
         create logical name OZ_SYSTEM_TABLE%OZ_UTIL_LOGON_MSG "OZONE experimental system" "Authorized access only"
   

2. Create a password.dat file in /ozone/startup/ directory with this line in it:

         |root|pass|*|*|*|1000/5000|oz_cli.elf|OZ_LOAD_FS:/
   

   ... without any spaces. The password in this example is pass. There really isn't anything special about the name root. The thing that makes this entry magic are the *s in there that give it unlimited access to everything. The 1000 says to run things by default as priority 1000. The 5000 means this user can start things up to priority 5000.

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 ;). You need something like this in the startup file (boothard.cli):

create logical name  -kernel OZ_SYSTEM_TABLE%OZ_IP_HOSTNAME <its host name like ozonx.nii.net>
#
create logical table -kernel OZ_SYSTEM_DIRECTORY%OZ_IP_SERVICES
