NetBSD/i386 _VER 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 (the unpacked binary distribution, without sources,
requires at least 65M without counting space needed for swap space,
etc), 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.)

Supported devices include:
	Floppy controllers.
	MFM, ESDI, IDE, and RLL hard disk controllers.
	SCSI host adapters:
		Adaptec AHA-154xA, -B, -C, and -CF 
		Adaptec AHA-174x
		Adaptec AIC-6260 and AIC-6360 based boards, including
			the Adaptec AHA-152x, Adaptec AHA-1460 (PCMCIA),
			and the SoundBlaster SCSI host adapter.  (Note
			that you cannot boot from these boards if they
			do not have a boot ROM; only the AHA-152x and
			motherboards using this chip are likely to be
			bootable, consequently.)
		Adaptec AHA-2x4x[U][W] cards and some onboard PCI designs
			using the AIC78X0 chip.  There is a known problem
			using this driver with AHA-2742 cards or AIC7770 or
			AIC78[56]0 based embedded designs and multiple
			targets, due to resource contention which is not
			handled well by NetBSD's higher-level SCSI subsystem.
		Adaptec AHA-3940[U][W] cards [b]
		Buslogic 54x (Adaptec AHA-154x clones)
		BusLogic 445, 74x, 9xx  (But not the new "FlashPoint" series
			of BusLogic SCSI adapters)
		Seagate/Future Domain ISA SCSI adapter cards, including
			ST01/02
			Future Domain TMC-885
			Future Domain TMC-950
		Symbios Logic (NCR) 53C8xx-based PCI SCSI host adapters:
			Acculogic PCIpport
			ASUS SC-200 (requires NCR BIOS on motherboard to
					boot from disks)
			ASUS SP3[G] motherboard onboard SCSI
			DEC Celebris XL/590 onboard SCSI
			Lomas Data SCSI adapters
			NCR/SYM 8125 (and its many clones; be careful, some
					of these cards have a jumper to set
					the PCI interrupt; leave it on INT A!)
			Promise DC540 (a particularly common OEM model of
					the SYM 8125)
			Tyan Yorktown
		Ultrastor 14f, 34f, and (possibly) 24f

Drivers for hardware marked with "[*]" are NOT present in kernels on the
distribution floppies.  Except as noted above, all drivers are present
on all disks.  Also, at the present time, the distributed kernels
support only one SCSI host adapter per machine.  NetBSD normally
allows more, though, so if you have more than one, you can use all of
them by compiling a custom kernel once NetBSD is installed.


Support for devices marked with "[+]" IS included in the "generic" kernels,
although it is not in the kernels which are on the distribution floppies.

Support for devices marked with "[b]" requires BIOS support for PCI-PCI
bridging on your motherboard.  Most reasonably modern Pentium motherboards
have this support, or can acquire it via a BIOS upgrade.

Hardware the we do NOT currently support, but get many questions
about:
	AMD PCscsi SCSI host adapters (though the PCnet portion of the
					PCnet-SCSI works fine)
	Intel EtherExpress 100 Fast Ethernet adapters.
	Multiprocessor Pentium and Pentium Pro systems.  (Though they should
		run fine using one processor only.)
	NCR 5380-based SCSI host adapters.
	PCI WD-7000 SCSI host adapters.
	PCMCIA ("PC Card") miniature IDE devices
	QIC-40 and QIC-80 tape drives.  (Those are the tape drives
		that connect to the floppy disk controller.)

We are planning future support for many of these devices.

To be detected by the distributed kernels, the devices must
be configured as follows:

ATA disks	wd0, wd1, ...
SCSI disks	sd0, sd1, ...

	For each SCSI and IDE controller found, the SCSI or ATA(PI) devices
	present on the bus are probed in increasing id order for SCSI and
	master/slave order for ATA(PI). So the first SCSI drive found will
	be called sd0, the second sd1, and so on ...
