| # $OpenBSD: README,v 1.4 1997/01/23 23:48:23 deraadt Exp $ | |||
| Initial test versions of a OpenBSD/sparc binaries install are available | |||
| at | |||
| ftp.openbsd.org:/pub/OpenBSD/snapshots/sparc | |||
| Some mirror sites may take a day or two to catch up. | |||
| The OpenBSD/sparc port runs on sun4c class machines, ie. the SS 1, 1+, | |||
| 2, IPC, IPX, SLC, and ELC. It works on most sun4m machines. It also runs | |||
| on most models of the sun4 line (however, not on the 4/400, 4/600). | |||
| The ftp directory contains a number of very large .tar.gz files in there, | |||
| as well as this document and a helper install script. | |||
| NOTE: THESE INSTRUCTIONS MAY CHANGE WITH EACH SNAPSHOT. | |||
| Until there are better instructions written, here's a rough idea: | |||
| 1. format and partition the disk using sunos. yup, OpenBSD/sparc uses | |||
| sunos disk labels. i am running a quantum 105 with these partition | |||
| sizes: | |||
| a: 28140 0 4.2BSD 1024 8192 16 # (Cyl. 0 - 133) | |||
| b: 16170 28140 unused 0 0 # (Cyl. 134 - 210) | |||
| c: 204540 0 unused 0 0 # (Cyl. 0 - 973) | |||
| g: 160230 44310 4.2BSD 1024 8192 16 # (Cyl. 211 - 973) | |||
| Filesystem 512-blocks Used Avail Capacity Mounted on | |||
| /dev/sd0a 26090 18846 4634 80% / | |||
| /dev/sd0g 149444 131496 3002 98% /usr | |||
| amd:43 0 0 0 100% /home | |||
| gecko:/usr/src 1549722 851783 542966 61% /usr/src | |||
| komodo:/usr/local 269346 243428 -1016 100% /usr/local | |||
| newt:/newt.usera 1128328 836910 178584 82% /tmp_mnt/newt/newt.usera | |||
| 2. newfs it using sunos. yup, the filesystem format is identical. | |||
| UFS hasn't changed much over the years. (If you can, there is | |||
| a performance benefit from newfs'ing using OpenBSD.) | |||
| If you newfs using the OpenBSD newfs command, be sure to use -O | |||
| to specify the `4.3BSD filesystem format' for your / partition, | |||
| otherwise you will not be able to boot. The SunOS boot blocks do | |||
| not understand the extended 4.4 filesystem format. | |||
| 3. put a SunOS /boot program in the root partition, and use | |||
| "installboot" to cause it to work. the "installboot" man page | |||
| says to do something like this: say you are running SunOS, and | |||
| the drive you are installing OpenBSD/sparc on is currently at | |||
| /dev/sd1. You have made the filesystems on that drive already. | |||
| # mount /dev/sd1a /mnt | |||
| # cp /boot /mnt/boot | |||
| # /usr/mdec/installboot -vlt /mnt/boot /usr/mdec/bootsd /dev/rsd1a | |||
| 4. extract the provided *.tar.gz files onto the disk. the file | |||
| "install.sh" will help you do this. | |||
| mount your partition(s) in a proper tree starting at /mnt. In the | |||
| same directory as your *.tar.gz files are, run "./install.sh". | |||
| (Now you may cut the head off the chicken and spray the blood over | |||
| your walls and ceiling. :-) | |||
| 5. copy /mnt/etc/fstab.sd to /mnt/etc/fstab and edit to match your | |||
| disk layout. | |||
| 6. the install script copies the kernel called "bsd.scsi3" to | |||
| /mnt/bsd. Two sample kernels are supplied: "bsd" and | |||
| "bsd.scsi3". | |||
| Unlike SunOS and the ROM, OpenBSD numbers scsi drives sequentially | |||
| as it finds them. The drive with the lowest scsi-id will be called | |||
| sd0. SunOS and the ROM map normally map sd0 to scsi-id 3. Thus, if | |||
| you have two drives, it's quite likely that OpenBSD will disagree with | |||
| the ROM. | |||
| The "bsd.scsi3" kernel gets around this problem, by hard-wiring | |||
| scsi-id#3 to sd0. The remaining drives will be dynamically mapped | |||
| to other sd* numbers. If you have more than one drive you will | |||
| want to use this kernel. | |||
| the "bsd" kernel expects your root drive to be at the standard | |||
| SunOS sd0==scsi-id#3 location. If you have a second drive at any | |||
| of scsi-id's 0, 1, or 2, this kernel will NOT work for you. If you | |||
| know what you are doing, you could use this kernel. | |||
| 7. your ROM may need some setup. make sure you boot from `new command mode'. | |||
| If your machine comes up and gives you a `>' prompt instead of `ok', type: | |||
| >n | |||
| ok setenv sunmon-compat? false | |||
| ok | |||
| this is needed because bsd cannot handle the old-mode yet, | |||
| and will firework on you. | |||
| you cannot use the security modes of the sparc ROM. sorry, same | |||
| problem as above. | |||
| ok setenv security-mode none | |||
| 8. if needed, swap your scsi id's. now try a reboot. initially I'd | |||
| suggest you boot "-bs", then try multiuser after that. if you boot | |||
| single-user the bsd incantation for making root read-write | |||
| is "mount -u /dev/sd0a /". alternatively, the command reboot is | |||
| found in /sbin. | |||
| 9. to boot from bsd by default, tell something like this to your | |||
| ROM. | |||
| >n | |||
| ok setenv boot-from sd(0,0,0)bsd | |||
| ok | |||
| please let me know of any errors in these instructions or in the | |||
| archives. if so i'll correct them. | |||
| good luck. | |||
