hardware revision 1.20 
1NetBSD/i386 _VER runs on ISA (AT-Bus), EISA, PCI, and VL-bus systems
2with 386-family processors, with or without math coprocessors.  It
3does NOT support MCA systems, such as some IBM PS/2 systems.  The
4minimal configuration is said to require 4M of RAM and 50M of disk
5space, though we do not know of anyone running with a system quite
6this minimal today.  To install the entire system requires much more
7disk space (the unpacked binary distribution, without sources,
8requires at least 65M without counting space needed for swap space,
9etc), and to run X or compile the system, more RAM is recommended.
10(4M of RAM will actually allow you to run X and/or compile, but it
11won't be speedy.  Note that until you have around 16M of RAM, getting
12more RAM is more important than getting a faster CPU.)

14Supported devices include:
15	Floppy controllers.
16	MFM, ESDI, IDE, and RLL hard disk controllers.
17	SCSI host adapters:
18		Adaptec AHA-154xA, -B, -C, and -CF

21			the Adaptec AHA-152x, Adaptec AHA-1460 (PCMCIA),
22			and the SoundBlaster SCSI host adapter.  (Note
23			that you cannot boot from these boards if they
24			do not have a boot ROM; only the AHA-152x and
25			motherboards using this chip are likely to be
26			bootable, consequently.)

158Drivers for hardware marked with "[*]" are NOT present in kernels on the
159distribution floppies.  Except as noted above, all drivers are present
160on all disks.  Also, at the present time, the distributed kernels
161support only one SCSI host adapter per machine.  NetBSD normally
162allows more, though, so if you have more than one, you can use all of
163them by compiling a custom kernel once NetBSD is installed.
164
165
166Support for devices marked with "[+]" IS included in the "generic" kernels,
167although it is not in the kernels which are on the distribution floppies.
168
169Support for devices marked with "[b]" requires BIOS support for PCI-PCI
170bridging on your motherboard.  Most reasonably modern Pentium motherboards
171have this support, or can acquire it via a BIOS upgrade.
172
173Hardware the we do NOT currently support, but get many questions
174about:
175	AMD PCscsi SCSI host adapters (though the PCnet portion of the
176					PCnet-SCSI works fine)
177	Multiprocessor Pentium and Pentium Pro systems.  (Though they should
178		run fine using one processor only.)
179	NCR 5380-based SCSI host adapters.
180	PCI WD-7000 SCSI host adapters.
181	QIC-40 and QIC-80 tape drives.  (Those are the tape drives
182		that connect to the floppy disk controller.)
183
184We are planning future support for many of these devices.
185
186To be detected by the distributed kernels, the devices must
187be configured as follows:
