*************** *** 48,61 **** worked it into shape for the NetBSD tree. Theo and Markus Wild worked on improving Chris' original SunOS compatibility code into a highly complete and reliable emulation. Chuck Cranor ported the sun4c code to ! the 8KB pagesized Sun4 architecture, and Theo merged this code in a way that would allow the same kernel and programs to run on either sun4c or sun4 machines (unlike Sun's separate kernel environments). This last change also required a rewrite of the device configuration code. Just after the NetBSD/sparc 1.0 release, Peter Galbavy wrote an ESP scsi device driver as a replacement for Chris' sparc-specific scsi ! code, this new driver unfortunately had some problems and was eventually ! replaced.

Theo continued working independently, and made a number of additions: ! P4 support, flexible boot strategy, a few graphics drivers with help ! from John Stone, and masses of bug fixes. Many people will be most ! interested that the ESP scsi driver has been completely replaced by ! Theo, and that it supports disconnect/reconnect.
Work on porting OpenBSD/sparc to the sun4m platform was started by Theo, but tendinitis problems with his wrists and the problems with the NetBSD ! core conspired, and he stopped work. Theo passed his initial sun4m work to Aaron Brown of Harvard, who was paid out of Margo Seltzer's research ! funds. This initial stuff consisted mostly of a few attempts at building pmap structure that could support all 3 MMU types efficiently. Also, ! David Miller of the S/Linux project got a little bit involved.
Theo and Jason Downs merged the NetBSD sparc code back into OpenBSD, making OpenBSD/sparc usable again. Jason Wright wrote a few new SBus Ethernet ! drivers with information from the S/Linux project and has merged a few bits from NetBSD sources to improve the stability of this architecture.

! Currently, all the hardware listed in the ! supported hardware list section below boots ! multi-user, and supports enough (if not all) of the on-board devices to ! be generally useable. ! A small set of third-party SBus cards are also supported.
! The X-Window system is working on all supported frame buffers, including ! multi-head configurations. ! No accelerated server is provided at the moment, although this is being ! worked on.

+ The last supported OpenBSD/sparc release is + OpenBSD 3.2. + Here are the + + OpenBSD/sparc 3.2 installation instructions + . +
+ ++ Snapshots are made available from time to time, in + this location + as well as in a few + mirrors. + Here are the + + OpenBSD/sparc snapshot installation instructions + as well. +
+ ++ There are several installation media provided, so that + OpenBSD/sparc can be installed or upgraded via CD, floppy boot images on + sun4c and sun4m, miniroot images for machines without floppies + (and sun4 machines), as well as network and diskless installs.
! Booting off the CD provides a small ffs filesystem with a kernel containing
! a GENERIC kernel with drivers for all devices found on Sparc machines.
! For the latest list of drivers available on this image, take a look at the
! GENERIC
! kernel configuration file.
! The CD can be booted off the OpenPROM prompt with
!
! boot cdrom 3.2/sparc/bsd.rd !!
! Booting off the floppy provides a small ffs filesystem with a kernel
! containing drivers for the most popular devices found on Sparc machines.
! For the latest list of drivers available on this image, take a look at the
! RAMDISK
! kernel configuration file.
! The floppy can be booted off the OpenPROM prompt with
!
! boot floppy !!
! The miniroot provides the same installation environment as the bootable CD, ! and is intended for easy bootstrap if there is already an operating system ! installed on the machine. ! After dumping the miniroot to the primary swap partition with dd, the ! miniroot can be booted off the OpenPROM prompt with a command such as !
! boot disk:b !! (the disk designation may be different, depending on the chosen swap ! partition). !
! Using a diskless setup, it is also possible to boot the OpenBSD/sparc ! boot loader, boot.net, from the network via tftp, and access ! the bsd.rd standalone miniroot over NFS. ! Refer to the ! diskless(8) ! manual page for details on how to setup a network boot environment. !
