CHAPTER 1 Introduction
This supplement provides information about the supported hardware for
LynxOS 3.0. Lynx defines “supported hardware” as products that are part of
the Lynx test suite and tested as part of the normal development and
verification cycle. Some products are presumed to be supported by LynxOS
because they are similar to “supported hardware.”
LynxOS 3.0 supports X86, PowerPC, 68K, and SPARC processor families in
both Native and Cross Development environments. The chapters within this
guide describe the hardware details for each of these families.
In addition, Lynx provides porting kit and source code products to customers
who wish to port LynxOS to custom hardware that uses a CPU from one of
the basic processor families supported by LynxOS.

CHAPTER 2 LynxOS for X86
Processor Support
Intel 386, 486, Pentium, Pentium Pro , and Pentium II.
NOTE: Intel 386SX and Intel 486SL/SX-based systems require a hardware
floating point co-processor for LynxOS installation and development. Without
the co-processor, these systems can only be targets for LynxOS applications
that do not use floating point instructions.
Bus Architectures
ISA, EISA, VLB, and PCI
Installation Requirements
Main Memory
• 4 MB minimum (less if using the LynxOS scalable kernel
technology)
• 8 MB required for Development System
• 16 MB or greater recommended for full Development System with
X and Motif.
NOTE: If your system has less than 24 MB of physical memory, you must enable
Virtual memory (VM) to use the full LynxOS Development System with X and
Motif. Virtual memory to physical memory must be at least 2:1.

Native and Cross Development
LynxOS and its native development tools run directly on the target platforms
listed in “Processor Support” on page 3. This is a unique benefit relative to
other real-time operating systems that require a cross development system to
develop and debug applications.
In addition, LynxOS provides cross development environments for SunOS
4.1.x/5.1 or Solaris (up to 2.5) on Sun workstations, AIX, Windows NT, and
Windows 95.
Booting Over the Network
With the optional Netboot Package, a diskless target can be booted over the
network from a server. This package contains a network controller-specific
64KB PROM. The LynxOS Netboot Package is available for the following
network controllers:
• SMC EtherCard Elite Ultra
• SMC EtherCard Plus Elite
• SMC EtherEZ (ISA)
• SMC EtherPower Combo
- SMC8432BT (10 Mbit)
- SMC9332BDT (10 and 100 Mbit)
• Western Digital EtherCard Elite
- WD8003E EtherCard Plus
