-OpenBSD/i386 2.1 runs on ISA (AT-Bus), EISA, PCI, and VL-bus systems
-with 386-family processors, with or without math coprocessors.  It
-does NOT support MCA systems, such as some IBM PS/2 systems.  The
-minimal configuration is said to require 4M of RAM and 50M of disk space,
-though we do not know of anyone running with a system quite this minimal today.
-To install the entire system requires much more disk space, and to run X
-or compile the system, more RAM is recommended.  (4M of RAM will
-actually allow you to run X and/or compile, but it won't be speedy.
-Note that until you have around 16M of RAM, getting more RAM is more
-important than getting a faster CPU.)
+OpenBSD/powerpc 2.1 runs on ISA (AT-Bus), and PCI buses

 	Miscellaneous:
-
-Drivers for hardware marked with "[*]" are NOT included on the
-distribution floppies.  Except as noted above, all other drivers are
-present on both kernel-copy disks.  Also, at the present time, the
-distributed kernels support only one SCSI host adapter per machine.
-OpenBSD normally allows more, though, so if you have more than one, you
-can use all of them by compiling a custom kernel once OpenBSD is
-installed.
-
-Support for devices marked with "[+]" IS included in the "generic" kernels,
-although it is not in the kernel on the installation floppy.
-
-
-Hardware the we do NOT currently support, but get many questions
-about:
-	Adaptec AIC-7770-based SCSI host adapters (including the
-		Adaptec AHA-274x, AHA-284x families).
-	NCR 5380-based SCSI host adapters.
-	APM power management -- if your system supports it, turn it off!
-	QIC-40 and QIC-80 tape drives.  (Those are the tape drives
-		that connect to the floppy disk controller.)
-	WD-7000 SCSI host adapters.
-	PCI-PCI bridges and cards which include them, such as the AHA-394x
-		SCSI host adapter and some DC21x4x-based multi-Ethernet cards.
-	Multiprocessor Pentium and Pentium Pro systems.  (Though they should
-		run fine using one processor only.)
-	Intel EtherExpress 100 Fast Ethernet adapters.
-
-We are planning future support for many of these devices.
-
-To be detected by the distributed kernels, the devices must
-be configured as follows:

-SPECIAL CARE FOR SMC ULTRA ELITE
---------------------------------
-
-
-Note for SMC Elite Ultra ethernet card users:  The Elite Ultra is very
-sensitive to how it's i/o port is treated.  Mistreating it can cause
-a number of effects -- everything from the card not responding when the
-kernel probes, or the soft configuration being corrupted or wiped completely.
-
-By default, the kernel ships with device ed2 configured for the 'default'
-Elite Ultra locations, comprising of port 0x300, irq 10, and memory location
-0xcc000.  This matches a hard coded jumper on the board as well a common
-soft config setting.
-
-Unfortunately, the kernel's autconfiguration process (specifically, some
-of the devices it probes for) cause conflicts with the SMC Elite Ultra, and
-very often cause it to lose it's configuration and fail it's own probe.
-If thise happens, you must boot the computer into DOS, and run the EzSetup
-program available from SMC.  The complete URL of which is 
-ftp://ftp.smc.com/pub/nics/ethernet/elite_ultra/gez122.exe.  This program
-will allow you to reconfigure and recover a card that has lost it's
-configuration with a minimum of hassle.
-
-In order to avoid blowing away the card, one *must* use the run-time kernel
-configuration system when booting the Install kernel.  This is done by
-giving the -c flag to the initial boot request.  Following the loading of
-the kernel, the user is presented with a
-
-UKC>
-
-prompt.  At this prompt, as variety of commands may be issued, but the
-relevant one to getting the SMC Elite Ultra running is 'disable'.  The
-wt0, el0, and ie1 devices all need to be disabled.  This is done by typing
-'disable' followed by the name of the device, i.e., 'disable wt0', and
-pressing return.
-
-If, for some reason, your Elite Ultra is not configured at the 'default'
-location the kernel is expecting it, you may also use the 'change' command
-in the UKC system to modify where the kernel will look for it.  Typing
-'change ed2' will allow you to modify those settings.  Note that running the
-card at an i/o port of anything other then 0x300 at this point is not
-recommended, and is beyond the scope of this document-- by doing so you
-risk other device probes wreaking the havoc we are trying to avoid.
-
-When all three extra devices are disabled and any changes made, the
-'quit' command will exit the UKC.  The kernel should then boot, and find
-your Elite Ultra on device ed2.
