March 06, 1997



This file contains
(1) Overview
(2) Supported Adapters
(3) Required Files
(4) Configuring the Boot ROM

===========================================================================


(1) OVERVIEW
============

This README explains how to use the Remote Boot ROM Configuration utility
SKROMCFG to configure SK-NET Remote Boot ROM image files for SK-NET
adapters that have a Flash PROM installed.

After the Remote Boot ROM image file has been configured with SKROMCFG, it
must be programmed into the adapter's Flash PROM with the diagnostic tool
that comes with the SK-NET adapter or with a special Flash PROM programming
tool for the adapter.
***


(2) SUPPORTED ADAPTERS
======================

The SKROMCFG Remote Boot ROM Configuration utility supports all SK-NET
adapters that have a Flash PROM installed and for which a configurable Boot
ROM image file is available.
***


(3) REQUIRED FILES
==================

The following files are required:

	SKROMCFG.EXE	The Remote Boot ROM Configuration utility
	BOOTxyz.ROM	The Remote Boot ROM image file for adapter 'xyz'
	SKDIAGxyz.EXE	The Diagnostics tool for adapter 'xyz'
or
	FLASHxyz.EXE	The Flash PROM programming tool for adapter 'xyz'
***


(4) CONFIGURING THE BOOT ROM
============================

Step 1:	Copy the Remote Boot image file, which you want to configure, and
	SKROMCFG.EXE to your working directory.

	Note:	The Remote Boot image file will be overwritten with the new
		selected configuration. Therefore, you should always keep a
		backup copy of the original image file.

Step 2:	Start the configuration utility SKROMCFG by either typing:

		SKROMCFG <Enter>
	or
		SKROMCFG <name of Remote Boot image file> <Enter>

	Note:	You can operate the configuration utility SKROMCFG on any
		computer, not necessarily on the computer, in which the
		adapter with the Boot ROM is installed.

	After SKROMCFG starts, the window "Select Boot ROM Configuration"
	is displayed.

	If you did not specify the name of the Remote Boot image file on
	the command line, enter the name in the field "Name of Boot ROM
	image file" and press <Enter>.

	SKROMCFG will now read the current configuration information from
	the image file.

Step 3:	You may now select the desired configuration by changing the
	contents of the fields in the "Select Boot ROM Configuration"
	window. Use the <Up> and <Down> arrow or <Tab> and <Shift-Tab> keys
	to select a field. The following fields are available:

	"Name of Boot ROM image file [..]"
	This field shows the name of the image file that you are currently
	configuring. The contents of this field cannot be changed once the
	name has been entered and the configuration has been read.


	Move to one of the following fields and press <Spacebar> or press
	'x', if you want to select the option of that field.

	Note:	You can only select one field out of the list of fields
		described below that begin with "( )". On the screen, the
		currently selected field shows "(*)".

	"( ) Wait for keystroke"
	Select this option, if you want the Boot ROM to wait for one of
	the two possible keystrokes specified in the "Keystroke for ..."
	fields explained below.

	"( ) On timeout boot from network"
	Select this option, if you want the Boot ROM to either wait for one
	of the two possible keystrokes (as with the "Wait for keystroke"
	option) or to automatically boot from the network after the time
	specified in the "Timeout in seconds" field (explained below) has
	elapsed.

	"( ) On timeout boot from disk"
	Select this option, if you want the Boot ROM to either wait for one
	of the two possible keystrokes (as with the "Wait for keystroke"
	option) or to automatically boot from disk after the time specified
	in the "Timeout in seconds" field (explained below) has elapsed.

	"( ) Always boot from network"
	Select this option, if you want the Boot ROM to always boot from
	the network.

	Note:	The computer will still boot from the diskette drive, if a
		bootable diskette is inserted.

	Caveat:	When this option is selected for a computer that does not
		have a floppy disk drive, the target computer cannot be
		booted when the network is down or malfunctioning. In this
		case, or if you want to boot the computer from hard disk,
		the adapter with the Boot ROM must be removed or the ROM
		must be disabled.

	"( ) Always boot from disk"
	Select this option, if you want the Boot ROM to always boot from
	disk. (Note that, if there is no disk boot device installed, the
	Boot ROM will always boot from the network.)


	"IPX frame type auto-detection:"
	This heading and its associated fields are only available for the
	IPX Remote Boot ROM.

	If available, enable or disable one or more of the following
	options to configure the IPX frame types, which will be used in the
	IPX Frame Type Auto-detection during the boot process.

	Note:	The IPX Frame Type Auto-detection mechanism uses the IPX
		frame types selected here to automatically determine the
		IPX frame type used by the fileserver. The default is to
		enable all available IPX frame types. If, however, the
		fileserver is connected to a distant network behind a
		bridge and the distant network is of a different network
		topology than the local network (e.g. local=Ethernet,
		distant=FDDI), it might be necessary to disable some of the
		possible frame types.

	Move to the desired field and press <Spacebar> or press 'x' to
	toggle between "enabled" and "disabled". When enabled, the field
	shows "[x]". When disabled, the field shows "[ ]".

	Below, replace "topo" with the actual network topology, which you
	are using (either ETHERNET, FDDI, or TOKEN-RING).

	"[ ] topo_802.2"
	Enable this option, if you want the Boot ROM to use the IEEE 802.2
	IPX frame type (with SAP=E0h) in the IPX Frame Type Auto-detection.

	"[ ] topo_SNAP"
	Enable this option, if you want the Boot ROM to use the SNAP IPX
	frame type (with type=8137h) in the IPX Frame Type Auto-detection.

	"[ ] ETHERNET_802.3"	(Ethernet only)
	Enable this option, if you want the Boot ROM to use the
	ETHERNET_802.3 IPX frame type in the IPX Frame Type Auto-detection.

	"[ ] ETHERNET_II"	(Ethernet only)
	Enable this option, if you want the Boot ROM to use the ETHERNET_II
	IPX frame type (with type=8137h) in the IPX Frame Type
	Auto-detection.


	"Name of boot image file:"
	This heading and its associated field are only available for
	the IPX Remote Boot ROM.

	"[NET$DOS].[SYS]"
	This field holds the name of the IPX boot image file in the
	SYS:\LOGIN directory of the server, which will be used in the
	remote boot process.

	"Startup message [..]"
	This field holds the message, which the Boot ROM will print to the
	screen at startup. Depending on the selected configuration, the
	Boot ROM will wait for one of the two possible keystrokes and show
	the remaining time in seconds before automatically booting from
	the configured boot device.

	The startup message may contain the following special characters:

		char	action
		----	----------
		\a	alert
		\b	backspace
		\f	* form feed
		\n	new line
		\r	carriage return
		\t	* horizontal tab
		\v	* vertical tab
		\\	escape character

		* = does not work on most computers

	Example:
		If you choose the "( ) On timeout boot from network"
		option, you might enter the following startup message:

		[<F1> = net\n<F2> = disk\n\nTimeout before net boot: ]

		...which will cause the following screen output:

			<F1> = net
			<F2> = disk

			Timeout before net boot: xxxx

		(where "xxxx" is the remaining time in seconds)


	To select the user-defined keystrokes for booting from network or
	from disk, use the following two fields:

	"[..] Keystroke for network boot"
	This field shows the key, which the user may press during startup
	to instruct the Boot ROM to boot from the network. When this field
	has been selected, press <Spacebar> and then press the desired key,
	which you wish to be the key for the network boot.

	"[..] Keystroke for disk boot"
	This field shows the key, which the user may press during startup
	to instruct the Boot ROM to boot from disk. When this field has
	been selected, press <Spacebar> and then press the desired key,
	which you wish to be the key for the disk boot.

	Note:	These fields are only available, if neither of the
		"( ) Always boot from ..." options has been selected.


	"Timeout in seconds (1..3598) [..]"
	This field holds the number of seconds before the Boot ROM boots
	from the device selected by an "On timeout boot from ..." field.
	Note that this field is not available, if any other than one of
	the following two options has been selected.


	"< OK >"
	Anytime, you may press <Enter> to select this field. You will then
	be prompted "Save Configuration?". Select "Yes" and press <Enter>
	to save the new configuration. Select "No" and press <Enter> to
	return to the "Select Boot ROM Configuration" window.


	"< Cancel >"
	If you select this field and press <Enter>, you will be prompted
	"Cancel Configuration and Exit?". Select "Yes" and press <Enter> to
	cancel the new configuration and exit the program. Select "No" and
	press <Enter> to return to the "Select Boot ROM Configuration"
	window.

Step 4:	After the new configuration has been saved, the Boot ROM image file
	must be programmed into the Flash PROM of the SK-NET adapter. This
	may be done by using either the diagnostic tool or the Flash PROM
	programming tool for the adapter.

	Note:	Programming the Flash PROM can only be performed on the
		computer that has the adapter with the Flash Boot PROM
		installed.

	a) If you are using the diagnostic tool SKDIAGxyz.EXE, please
	follow the instructions from the README of that tool.

	b) If you are using the Flash PROM programming tool FLASHxyz.EXE,
	please follow the instructions from the README of that tool.

Step 5:	Boot the computer by pressing <Ctrl-Alt-Del>.
