hardware revision 1.6 
1NetBSD/i386 1.2A 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 space,
5though we do not know of anyone running with a system quite this minimal today.
6To install the entire system requires much more disk space, and to run X
7or compile the system, more RAM is recommended.  (4M of RAM will
8actually allow you to run X and/or compile, but it won't be speedy.
9Note that until you have around 16M of RAM, getting more RAM is more
10important than getting a faster CPU.)

12Supported devices include:
13	Floppy controllers.
14	MFM, ESDI, IDE, and RLL hard disk controllers.
15	SCSI host adapters:
16			[Adaptec host adapters only on kcadp floppy]
17		Adaptec AHA-154xA, -B, -C, and -CF 
18		Adaptec AHA-174x
19		Adaptec AIC-6260 and AIC-6360 based boards, including
20			the Adaptec AHA-152x and the SoundBlaster SCSI
21			host adapter.  (Note that you cannot boot from
22			these boards if they do not have a boot ROM;
23			only the AHA-152x and motherboards using this chip
24			are likely to be bootable, consequently.)
25		Adaptec AHA-2x4x[U][W] cards and some onboard PCI designs
26			using the AIC78X0 chip.  There is a known problem
27			using this driver with AHA-2742 cards or AIC7770 or
28			AIC78[56]0 based embedded designs and multiple
29			targets, due to resource contention which is not
30			handled well by NetBSD's higher-level SCSI subsystem.
31		Adaptec AHA-3940[U][W] cards [b]
32		Buslogic 54x (Adaptec AHA-154x clones; driver on kcadp floppy)
33
34			[Other host adapters only on kcoth floppy]
35		BusLogic 445, 74x, 9xx  (But not the new "FlashPoint" series
36			of BusLogic SCSI adapters)
37                Seagate/Future Domain ISA SCSI adapter cards, including
38                        ST01/02
39                        Future Domain TMC-885
40                        Future Domain TMC-950
41		Symbios Logic (NCR) 53C8xx-based PCI SCSI host adapters:
42			Acculogic PCIpport
43			ASUS SC-200 (requires NCR BIOS on motherboard)
44			ASUS SP3[G] motherboard onboard SCSI
45			DEC Celebris XL/590 onboard SCSI
46			Lomas Data SCSI adapters
47			NCR/SYM 8125 (and its many clones; be careful, some
48				      of these cards have a jumper to set
49				      the PCI interrupt; leave it on INT A!)
50			Promise DC540 (a particularly common OEM model of
51				       the SYM 8125)
52			Tyan Yorktown
53		Ultrastor 14f, 34f, and (possibly) 24f
54		Western Digital WD7000 SCSI host adapters (ISA cards only)
55
56	MDA, CGA, VGA, SVGA, and HGC Display Adapters.  (Note that not
57		all of the display adapters NetBSD/i386 can work with
58		are supported by X.  See the XFree86 FAQ for more

134Drivers for hardware marked with "[*]" are NOT included on the
135distribution floppies.  Except as noted above, all other drivers are
136present on both kernel-copy disks.  Also, at the present time, the
137distributed kernels support only one SCSI host adapter per machine.
138NetBSD normally allows more, though, so if you have more than one, you
139can use all of them by compiling a custom kernel once NetBSD is
140installed.
141
142
143Support for devices marked with "[+]" IS included in the "generic" kernels,
144although it is not in the kernels which are on the distribution floppies.
145
146Support for devices marked with "[b]" requires BIOS support for PCI-PCI
147bridging on your motherboard.  Most reasonably modern Pentium motherboards
148have this support, or can acquire it via a BIOS upgrade.
149
150Hardware the we do NOT currently support, but get many questions
151about:
152	AMD PCscsi SCSI host adapters (though the PCnet portion of the
153				       PCnet-SCSI works fine)
154        Intel EtherExpress 100 Fast Ethernet adapters.
155        Multiprocessor Pentium and Pentium Pro systems.  (Though they should
156                run fine using one processor only.)
157        NCR 5380-based SCSI host adapters.
158	PCI WD-7000 SCSI host adapters.
159	PCMCIA ("PC Card") devices, including some miniature "IDE" hard disks.
160	QIC-40 and QIC-80 tape drives.  (Those are the tape drives
161		that connect to the floppy disk controller.)
162
163We are planning future support for many of these devices.
164
165To be detected by the distributed kernels, the devices must
166be configured as follows:
