hardware revision 1.15 
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.)
13
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.)

48					the SYM 8125)

150Drivers for hardware marked with "[*]" are NOT present in kernels on the
151distribution floppies.  Except as noted above, all drivers are present
152on all disks.  Also, at the present time, the distributed kernels
153support only one SCSI host adapter per machine.  NetBSD normally
154allows more, though, so if you have more than one, you can use all of
155them by compiling a custom kernel once NetBSD is installed.
156
157
158Support for devices marked with "[+]" IS included in the "generic" kernels,
159although it is not in the kernels which are on the distribution floppies.
160
161Support for devices marked with "[b]" requires BIOS support for PCI-PCI
162bridging on your motherboard.  Most reasonably modern Pentium motherboards
163have this support, or can acquire it via a BIOS upgrade.
164
165Hardware the we do NOT currently support, but get many questions
166about:
167	AMD PCscsi SCSI host adapters (though the PCnet portion of the
168					PCnet-SCSI works fine)
169	Intel EtherExpress 100 Fast Ethernet adapters.
170	Multiprocessor Pentium and Pentium Pro systems.  (Though they should
171		run fine using one processor only.)
172	NCR 5380-based SCSI host adapters.
173	PCI WD-7000 SCSI host adapters.
174	PCMCIA ("PC Card") miniature IDE devices
175	QIC-40 and QIC-80 tape drives.  (Those are the tape drives
176		that connect to the floppy disk controller.)
177
178We are planning future support for many of these devices.
179
180To be detected by the distributed kernels, the devices must
181be configured as follows:
