BSD/386
Version 1.1
Questions and Answers
BSD/386 Version 1.1 is the second production release of BSDI's ground-breaking
UNIX-like operating system for your PC or compatible. Version 1.1 is based on
the Net2 release of the Computer Systems Research Group at University of Cali-
fornia, Berkeley and includes Net2's features and capabilities. Additionally,
it includes MIT's X Window system and other software from a wide variety of
sources. BSDI has augmented these software bases with all the modules needed
to provide a complete operating system and set of utilities.
Version 2.0, due at the end of November, 1994, moves the code base to Berke-
ley's 4.4BSDLite release. The operating system name will change with the
November release.
BSDI's operating system releases are unique in their offering of supported
base systems software with almost complete source code. We invite you to read
these questions and answers to clarify the many features and benefits of
BSDI's BSD/386.
Question: What is BSD/386?
Answer: BSD/386 is an IEEE POSIX-compliant operating system for 386, 486,
and Pentium PC-compatibles. It includes a wide range of function-
ality, a rich set of utilities, and the X11R5 Window System.
BSD/386 can be purchased as a ready-to-boot binary-only system and,
if desired, one can additionally purchase the sources that generate
those binaries.
BSD/386's strengths include its ability to act as a gateway to the
Internet (no external router is required), its complete software
development system, and its low license fees when used as a soft-
ware distribution platform or embedded system.
As of August, 1994, BSDI has garnered over 2,000 customers around
the world.
Question: What hardware is required to run BSD/386?
Answer: BSD/386 runs on 386, 486, and Pentium PC-compatible systems with
ISA or EISA bus architectures (localbus versions of supported cards
work also). You'll need at least 4 MB of memory for the base oper-
ating system or at least 8 MB if you intend to use the X Window
System. Any console display will work for text mode. If you wish
to run the X Window System, your PC will need a color SVGA- or VGA-
compatible display for its console. You'll also need a standard
PC/AT keyboard and a 1.44MB 3.5" floppy drive and controller to
install the system.
BSD/386 does not currently support Micro-Channel Architecture (MCA)
machines or peripherals.
You will need a hard-disk drive on which to install the operating
system. You can use IDE, ESDI, RLL, MFM or SCSI disk drives.
BSD/386 supports the Adaptec 154xB, 154xC, 154xCF, and 174xA SCSI
adapters, and the BusLogic (BusTek) BT-542B (ISA), BT-742 (EISA),
BT-747 (EISA), BT-445S (VLB), and BT-946 (PCI) SCSI adapters. An
experimental Adaptec 1520 driver is also available. Just about any
SCSI disk will work with the supported adapters on BSD/386, includ-
ing SCSI disks much larger than 1 GByte (e.g., the new Seagate 9GB
drive).
The operating system requires some disk space to be allocated for
swap space. This is used to increase the memory available to
applications beyond the actual memory installed in machine (aka
virtual memory). A typical system requires 16 or 32MB of swap
space (or larger on systems with heavy usage).
For ease of installation, the system is broken into two dozen dif-
ferent sections; an installation program allows you to select those
you wish to install from a menu.
The operating system and utilities sizes break down as follows
(grouped here by common selection; most individual sections range
from 5 to 15MB):
Package Set Size
---------------------------------------------------------------
Base OS, Utilities, Networking, Development tools 52MB
Contributed Software (GNU and other) 26MB
Games, MH, Ghostscript, Emacs, TeX, ISODE 49MB
X11R5 Server, Fonts, X11 Clients, X11 Development tools 68MB
The source package sizes are as follows:
Packages Size
--------------------------------------
BSD/386 Kernel sources 7MB
Library and Utilities sources 222MB
X11R5 sources 116MB
A full install of all binaries and sources requires a total of
540MB. CD-ROM users have access to all the sources and binaries
directly from the CD-ROM. Most of the software packages can be
compiled directly from the CD-ROM.
BSD/386 is distributed on CD-ROMs, QIC-150 cartridges, Exabyte 8mm
tapes, and 4mm DAT tapes. For installation, you will need access
to a device that supports one of the distribution media types. We
do not currently ship BSDI on 200 floppy disks because we think the
size of the release in that format would be cumbersome.
Most SCSI CD-ROM and tape drives (e.g., Maynard/Archive 2150S,
Exabyte 8250) work with BSD/386 when attached to a supported SCSI
controller.
For non-SCSI tape or CD-ROM installation, the choices are limited
to the devices that BSD/386 directly supports. BSD/386 has drivers
for the WangTek 5150PK QIC-02 tape drive and controller (which,
despite its name, supports the QIC-150 tapes) and the Everex
EV-811, EV-831, and EV-833 tape drives and controllers. For non-
SCSI CD-ROM, BSD/386 supports the Mitsumi LU002, LU005, and FX001
ISA-based CD-ROM readers (available from BSDI and elsewhere) with
their own controllers.
With BSD/386, you can also load the distribution over your PC's
Ethernet (or even a serial SLIP link) from a remote system that
supports the rsh protocol and has the required hardware
(QIC-150/8mm/4mm tape drive or CD-ROM drive with support for
ISO9660/Rock Ridge CD-ROMs).
Question: What hardware is supported under BSD/386?
Answer: BSD/386 supports a wide variety of hardware. BSD/386 supports a
floating point coprocessor (like a 387, or the built-in coprocessor
on a 486DX, or other equivalent hardware). If floating point hard-
ware is not available the operations are automatically emulated in
software.
BSD/386 supports almost all SCSI disks, tapes, and CD-ROM drives
via the Adaptec 154xB, 154xC, 154xCF, and 174xA SCSI controllers,
or the BusLogic (BusTek) BT-542B (ISA), BT-742 (EISA), BT-747
(EISA), BT-445S (VLB), and BT-946 (PCI) SCSI adapters. An experi-
mental Adaptec 1520 driver is also available.
BSD/386 supports 256MB of extended memory installed on ISA and EISA
bus machines.
BSD/386 supports most Ethernet controllers: Western Digital
(WD)/Standard Microsystems Corp. (SMC) 8003/8013 EtherCard
PLUS/Elite series/Ultra, SMC Ultra, 3COM 3C501 (EtherLink), 3C503
(EtherLink II), 3C505 (EtherLink Plus), 3C507 (EtherLink 16),
3C509/3C579 (EtherLink III), the Novell NE1000 & NE2000, the TNIC
1500, the Allied Telesys RE2000/AT-1700 Series (experimental), HP
EtherTwist (experimental), the Xircom PocketEthernet II and III,
and the Intel EtherExpress 16 (experimental).
BSD/386 supports the SDL Communications RISCom/N1 and RISCom/H2
high-speed synchronous interface cards. These provide a point-to-
point bit-synchronous serial connection with speeds up to 4 Mb/s
using HDLC frame format. BSD/386 supports Cisco HDLC encapsulation
(for connecting to Cisco routers) and PPP (Point-to-Point Protocol)
over these connections. These can be used to network over standard
56K DDS leased lines. BSD/386's WAN routing capability may enable
you to use your PC as a server and a router - thus removing the
requirement to buy an expensive dedicated router.
BSD/386 supports standard COM and LPT ports and most serial mice.
The SDL RISCom/8, MAXpeed, Digiboard, Specialix (experimental), and
AST-4 multiport serial cards are supported. The MAXpeed and Digi-
board drivers can only be supplied in binary form. Call BSDI for
availability of the Digiboard PC/16Em.
BSD/386 supports any standard monochrome or color display con-
troller in text mode. For screens larger than 640x480, the X Win-
dow System requires color SVGA or VGA cards and enough memory for
the virtual screen size desired (usually about 1 MB). If you want
a good middle-of-the-road card, the ATI Graphics Ultra and its
higher-performance kin, the ATI Graphics Ultra Pro are both nice.
The X Window System now supports VGA-size screens, but they are
quite small for multiple windows, of course.

Video adaptors specifically for the ISA, EISA, VLB, and PCI buses
are supported (providing their chips are supported, see the list
above).
Question: What about Ethernet adapters for laptops?
Answer: BSD/386 supports the Xircom PocketEthernet II and III parallel port
ethernet controllers which can be used in general operation and for
installation.
Question: What about PCMCIA?
Answer: PCMCIA is currently scheduled to be engineered in early 1995. Some
experimental drivers are available.
Question: Does BSD/386 require special hardware configurations?
Answer: BSD/386 includes an autoconfiguration facility that attempts to
probe your system to determine which peripherals are present.
Booting from the floppy uses a `generic' kernel which has a large
selection of devices--but not all of them.
The generic kernel supports the configuration in the following
table.
+------------------------------------------------------------------+

- The iomem addresses for WD/SMC, 3c503, and 3c509 Ethernets are
automatically configured by BSD/386--no special hardware configu-
ration by the user is necessary. The port number for the 3c509
is also set by the kernel. The 3c509 uses port 0x100 during
autoconfiguration--this can conflict with another device.
o BSD/386 supports WD/SMC Ethernet at 0x280, 0x2A0, 0x2E0, 0x300,
0x320, 0x340, 0x360, 0x380, 0x3A0, and 0x3E0.
= BSD/386 supports the 3C503 at 0x280, 0x2A0, 0x2E0, 0x300, 0x310,
0x330, and 0x350.
o Parallel printer ports and Pocket Ethernet adapters at port 0x3BC
are known as unit 2 (lp2, pe2 or xir2).
The BSD/386 kernel supports the floating point coprocessor or auto-
matically emulates the hardware if none exists.
If your configuration doesn't conform to these specifications you
will need to reconfigure it to match. It is extremely important
that you avoid conflicts in the IRQ, I/O Port, and I/O memory
addresses of peripherals.
The following devices are supported but are not configured in
generic kernel. When you configure them into your kernel you can
customize the configurations. Details of individual device config-
uration can be found in section 4 of the online manual pages.

Question: Can I run SCO UNIX applications on BSD/386?
Answer: BSDI has shipped its beta version of SCO UNIX compatibility. Lotus
1-2-3 and Word Perfect are currently up and running in our testing
laboratories. Some other applications work fine; some require
capabilities not yet implemented. Continued engineering and test-
ing should result in the SCO compatility mode being relatively com-
plete in the 2.0 release. Programs which do not exploit knowledge
of the SCO kernel should work perfectly.
Question: Can I run DOS applications on BSD/386?
Answer: BSD/386 supports an environment for running many DOS applications.
This environment uses the 8086/8088 emulation mode and supports up
to 4MB of RAM in extended memory. Most applications that don't
require special hardware or Microsoft Windows should run.
Question: How is BSD/386 installed? How long does it take?
Answer: BSD/386 boots to single user mode via a boot floppy. The running
operating system then copies files from tape or CD-ROM to the hard
disk. Once the hard disk is loaded, BSD/386 boots from there.
Installation speed varies with the speed of peripherals, particu-
larly the tape drive. The fastest tape drives reduce loading time
for the base system and the X Window System to under one hour; CD-
ROM installs go even faster.
Question: Can I share a disk between BSD/386 and other operating systems?
Answer: BSD/386 supports co-residency so that one hard disk can support as
many as four different operating systems, the DOS limit.
Question: Can I share disk files between BSD/386 and MS-DOS?
Answer: BSD/386 supports mounting MS-DOS filesystems directly into your
BSD/386 directory hierarchy. BSD/386 also supports the popular
mtools package for reading and writing DOS format filesystems (on
both floppies and hard disks). With doscmd, some MS-DOS applica-
tions can access BSD/386 files.
Question: Does BSD/386 support floating point operations?
Answer: BSD/386 supports floating point operations in hardware or, if no
floating point hardware is available, through emulation in soft-
ware.
Question: What standards does BSD/386 support?
Answer: BSD/386 supports the IEEE POSIX 1003.1 standard (though certifica-
tion has not yet been completed). BSDI has tracked the IEEE POSIX
1003.2 standard and is modifying utilities to conform. BSD/386
networking includes both the OSI and TCP/IP standards. The BSD/386
C compiler (gcc) supports ANSI C; all system headers comply with
ANSI-C's requirements. The X Window System (Version X11R5) is an
industry standard window system based on software from MIT.
Question: What filesystems does BSD/386 support?
Answer: BSD/386 supports the UFS filesystem (also known as the Fast
Filesystem) and a memory-based filesystem (known as MFS). The
filesystems support long file names and symbolic links. BSD/386
also supports the ISO-9660 and Rock Ridge filesystems, now in popu-
lar use for CD-ROMs. MS-DOS filesystems can also be mounted under
BSD/386.
Additionally, BSD/386 includes a re-implementation of Sun's NFS,
the industry standard for network file sharing. For reliable use
over low-speed or long-haul links (where traditional NFS fails),
you can use our TCP/NFS.
BSD/386 can also mount MS/DOS filesystems.
Question: How fast is BSD/386?
Answer: BSD/386's speed depends, of course, on the underlying hardware. A
486-based system with 33 MHz clock and reasonable SCSI disks per-
forms at about the same speed as a SPARCStation 1+; with a 50 MHz
clock, the 486 processors seem to benchmark at about 25 MIPS. A
486/50 can rebuild the entire kernel from scratch in just seven
minutes.
The new Pentium processors provide a quantum increase in speed.
Measurements of a P5/90 (90 MHz Pentium) yield 65-90 MIPS of per-
formance (depending on the benchmark), about 2.5 times faster than
speedy 486/66's.
Question: What compilers are included?
Answer: BSD/386 currently includes the GNU 1.42 gcc, and the GNU 2.5.8 gcc2
and g++ compilers.
Question: How can a full source license cost so little? What about the USL
license costs?
Answer: BSD/386 is not System V UNIX. BSDI passes the royalty savings
along to you.
Question: Is BSD/386 System V compatible?
Answer: Beyond IEEE POSIX standards, the X11 Window System, and the upcom-
ing SCO compatibility mode, no special System V compatibility is
supplied. BSD/386 is very compatible with other Berkeley-based
software environments (e.g., SunOS, Ultrix, and OSF/1) for compila-
tion of source code and general system administration.
Question: Can I redistribute BSD/386 to my friends for free?
Answer: No. Right now, BSDI distributes most domestic copies of BSD/386
directly through BSDI. Special licensing arrangements are avail-
able for VARs, OEMs, distributors, and educational institutions.
The BSD/386 source code contains a number of modules written by
BSDI to glue together the various components of the release. It
also contains a large amount of freely redistributable code. You
are free to redistribute those modules which are not marked as pro-
prietary.
Question: Can I redistribute BSD/386 to customers of my business?
Answer: Vertical marketers and others may wish to distribute binary copies
(or, very rarely, source copies) of BSD/386 as part of their prod-
uct. Contact BSDI for pricing information.
Question: What about using more than one copy at my site?
Answer: Binary right-to-use licenses are available for your site after you
have purchased a full-function binary license or a source license.
Contact BSDI for details.
Question: Can I share modifications to BSD/386 code with my friends or cus-
tomers? Can I post the modifications on Usenet?
Answer: Any software you develop using BSD/386 is yours to own, share,
and/or sell as you choose. Of course, if it includes software
which is proprietary to BSDI, we must ask you not to make the
source available to anyone not having a BSDI source license. We
feel that it's in everyone's best interests to make bug fixes and
improvements available to the entire community. Therefore, cus-
tomers are free to post reasonable diff's to the net (as long as
the post doesn't contain too much BSDI proprietary code).
Question: Is Motif available?
Answer: In the USA Motif is available from the ACC Bookstore (USA:
800-546-7274, info@acc-corp.com, Intl: +1 203-454-3242); In Europe,
contact Lasermon Ltd (+44 (0) 329 826444, info@lasermoon.co.uk).
Question: What documentation is provided with BSD/386?
Answer: Complete release and installation documentation is supplied. The
man pages are supplied online in both formatted and unformatted
forms.
