hardware revision 1.17 
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)

148Drivers for hardware marked with "[*]" are NOT present in kernels on the
149distribution floppies.  Except as noted above, all drivers are present
150on all disks.  Also, at the present time, the distributed kernels
151support only one SCSI host adapter per machine.  NetBSD normally
152allows more, though, so if you have more than one, you can use all of
153them by compiling a custom kernel once NetBSD is installed.
154
155
156Support for devices marked with "[+]" IS included in the "generic" kernels,
157although it is not in the kernels which are on the distribution floppies.
158
159Support for devices marked with "[b]" requires BIOS support for PCI-PCI
160bridging on your motherboard.  Most reasonably modern Pentium motherboards
161have this support, or can acquire it via a BIOS upgrade.
162
163Hardware the we do NOT currently support, but get many questions
164about:
165	AMD PCscsi SCSI host adapters (though the PCnet portion of the
166					PCnet-SCSI works fine)
167	Intel EtherExpress 100 Fast Ethernet adapters.
168	Multiprocessor Pentium and Pentium Pro systems.  (Though they should
169		run fine using one processor only.)
170	NCR 5380-based SCSI host adapters.
171	PCI WD-7000 SCSI host adapters.
172	PCMCIA ("PC Card") miniature IDE devices
173	QIC-40 and QIC-80 tape drives.  (Those are the tape drives
174		that connect to the floppy disk controller.)
175
176We are planning future support for many of these devices.
177
178To be detected by the distributed kernels, the devices must
179be configured as follows:
