BootWare/3C515 Configuration Supplement

BootWare version:  1.00


Adapters Supported:     3Com 3C515 Fast EtherLink ISA Adapter

INSTALLING THE BootWare ROM
BootWare/3C515 is installed in a 32-pin socket.  Consult the 3Com
EtherLink III Adapter Guide on the location of the 32-pin ROM
socket.

BootWare CONFIGURATION FACILITY
BootWare/3C515 features a built-in setup facility which may be used
to view or change the configuration of BootWare/3C515.  The setup
utility may be accessed by pressing <Ctrl><ALT><B> within 5 seconds
after the adapter is initialized, while the dots are being displayed
on the top left corner of the screen.

Only BootWare parameters (Boot Protocol, Default Boot, ROMShield &
Floppy/Hard Disk Boot) are configurable. Adapter settings such as I/O Base,
Interrupt Level, DMA are either determined by the system BIOS or set by
3Com configuration utility.

BootWare/3C515 ROM is 64K/16K-page mapped. Upon starting, BootWare
tries to determine whether or not the adapter is brought up. If yes,
BootWare sets proper ROM mapping itself.  On workstations with
Plug'n'Play BIOS, the 3C515 adapter is initialized by the system BIOS when
the workstation starts.  On the other workstations, mostly 486-based, ROM
configuration as well as BIOS parameters has to be set by the 3C515
configuration utility, 3C515CFG.EXE, supplied by 3Com. Also use this
utility to enable the ROM when it is disabled.

Run 3C515CFG.EXE to enable/remap the Boot ROM/set BIOS variables.
Select "Install" in the pull-down menu, then "Configure Adapter".
BIOS variables such as Media Type, I/O Port Address, Interrupt
Level, DMA Channel can be set either manually or by choosing "Auto
Configure".  To set Boot ROM mapping, choose "Boot ROM", select
"64 Kbytes" from the list and then choose a value for the
ROM Base address.

Environments Supported
BootWare/3C515 features six selectable boot protocols; Native
NetWare 802.2, Native NetWare 802.3, Native NetWare Ethernet_II,
RPL, BOOTP, and BOOTP/ARP.

NetWare Modes (Ethernet_802.2, Ethernet_802.3, Ethernet_II)
Three Ethernet frame types are supported: NetWare 802.2, NetWare
802.3, and NetWare Ethernet_II.  Choose a frame type that is
supported by your file server(s).  Note that NetWare v3.12 and v4.x
support NetWare 802.2 as the default frame type; all older NetWare
versions support 802.3 as the default.

When using ODI drivers, Novell's RPLODI utility must be loaded after
LSL, and before the ODI driver is loaded.  Do NOT run RPLFIX on the
boot image; DOS 5 & 6.X support is built-in.

RPL Mode
RPL mode supports Microsoft LAN Manager 2.X, Windows NT Server, IBM
LAN Server 3.0 & 4.0.  Remoteboot of various versions of DOS & OS/2
are supported, depending on the network operating system.

TCP/IP Modes (BOOTP and BOOTP/ARP)
TCP/IP mode requires a TFTP daemon and a BOOTP daemon to be loaded
at the host.  Most versions of DOS can be remote booted, along with
a communication service such as NFS.

        BOOTP Mode:     Used when the BOOTP daemon is on the same
                        server as the image file.

        BOOTP/ARP Mode: Used when the BOOTP daemon is on a different
                        server than the image file. After receiving the
                        reply from the BOOTP daemon, the workstation
                        will do an ARP (Ping) to find the
                        server with the image file.

Error Messages:

        Initialization failed...Could not find 3C515.
This message appears when 3C515 hardware is not found.

Rx2 Rx2 Rx2... Timeout waiting for reply from file server. Could be caused
by: - incompatible Ethernet standard (802.3 vs 802.2 vs Standard Ethernet
8137) - not connected to an active file server

BWUPDATE.EXE

BWUPDATE is a DOS-based configuration utility that allows you to
update and configure your BootWare/3C515 Boot ROM device.  In order
to use this utility the 3C515 ROM, the 3C515.OVL file should be
used in conjunction with BWUPDATE.

BWUPDATE facilities:

Update ROM: Update on-board ROM contents with specially encoded
                BootWare ROM image binary file.  Used in case of
                shipping of new BootWare version.

Display ROM information:        Show the current status of ROM, such
                                as selected protocol, BootWare type,
                                version number, etc.

Configure BootWare ROM:         Customize BootWare/3C515 ISA Boot ROM.

Write Sample config file:       Create a sample config file which can be
                                used in conjunction with BWUPDATE.EXE
                                in DOS command line input.

Exit Program:                   Exit BWUPDATE utility
