- This TOKODI.DOC accompanies DOSUP8.EXE which includes DOS ODI
- drivers for IBM Token-Ring and Lan Support NetWare Clients. The
- following file(s) are included:
-
- TOKEN COM 27381 4-12-93 6:27p
- LANSUP COM 21943 2-02-93 11:54a
- TOKODI DOC (this file)
-
- Token.com and lansup.com have been enhanced to include 'Least
- Significant Bit' first (LSB) node addresses per the 'IEEE canonical
- form' when sending frames above the Data-Link layer. Previously,
- token.com and lansup.com drivers provided 'Most Significant Bit'
- first (MSB) only when sending MAC header node address information
- above the Data-Link layer. This LSB ability provides node ID
- bit-reversal compatibility with IBM 8209 Bridges. Bit-reversals
- take place on all source and destination node addresses
- when 8209 bridges transfer frames from ethernet segments to
- token-ring segments unless "IPX Support" has been enabled on the
- 8209. The 8209 will not bit-reverse IPX (E0E003/AAAA03/8137) node
- addresses when "IPX Support" has been enabled. The new LSB feature
- of lansup.com and token.com allow compatibility with the 8209
- without "IPX Support" enabled. It is advised only to use the LSB
- parameter on the Token- Ring segments with 8209 bit-reversal
- enabled. (see paragraphs below on Bit-Reversals)
-
- Additionally, these drivers provide full compatibility with the
- latest IBM locally administered node address standard for
- Token-Ring adapters. In the past, IBM recommended that locally
- administered addresses for Token-Ring adapters fall within a range
- between and including the following addresses:
-
- 4000 0000 0000 to 4000 7FFF FFFF (HEX)
-
- IBM has expanded the range of recommended locally administered
- addresses to the following:
-
- 4000 0000 0000 to 7FFF FFFF (HEX)
-
- There are some restrictions that apply to the above changes. Some
- devices and/or programs may only be able to use decimal addresses.
-
- In this case, the following locally administered address range
- would be appropriate:
-
- 4000 0000 0000 to 7999 9999 9999 (HEX)
-
- It is recommended that 'NSSS FLASH N1005' be obtained from IBM for
- all details pertaining to the above LAA changes and associated
- restrictions.

- ********* USAGE **********
- The following NET.CFG file demonstrates the enhanced abilities and
- usage of lansup.com and token.com. Please refer to the Novell
- ODI shell for DOS manual (part #100-000871-001) for further
- information on individual parameters. Additional information
- regarding implementation of token.com and lansup.com is available
- in DOSODIWS.DOC found in DOSUP8.EXE also available on NetWire.
-

- LINK DRIVER Token (or Lansup)
- Node Address 444400002D43
- Slot 2
- Frame TOKEN-RING_SNAP LSB
- SAPS 2
- Link Stations 2
- ALTERNATE
- Max Frame Size = 2168

- *********** BIT-REVERSALS ********
- Bit-reversals are necessary because of the difference between
- ethernet adapters and token-ring adapters:
-
- Ethernet adapters transmit data onto the wire by transmitting one
- byte of data at a time in the following manner: Each byte of
- data is bit-wise right-shifted one bit at a time onto the wire
- until all 8 bits of the byte are transmitted onto the wire. The
- next byte of data is then loaded into the transmit register and the
- process repeats itself. The least significant bit, therefore, goes
- onto the wire first with ethernet adapters.
-
- Token-Ring adapters do the opposite. They take one byte of data
- and do a bit-wise left-shift one bit at a time onto the wire until
- all 8 bits of the byte are transmitted onto the wire. Another byte
- of data is then loaded into the transmit register for transmission.
-
- The most significant bit, therefore, goes onto the wire first.
-
- Therefore, the byte 'AA (hex)' on an ethernet wire would appear as
- the byte '55 (hex)' on a Token-Ring wire after being bit-reversed
- by an IBM 8209 Ethernet to Token-Ring Bridge.

- ************* TOKODI MODIFICATION HISTORY **************
-
- 3-12-91: Initial release of TOKODIFT.ZIP beta drivers.
-
- 6-3-92: Lansup.com has been updated to allow frame sizes above
- 1K during RPL. A new "OPEN" parameter for the NET.CFG
- has been added. This feature allows lansup.com to open
- the token-ring adapter and set the frame size. If
- dxmt0mod.sys is also loading, one of two actions must be
-
- performed: (1) set "o=n" on the dxmt0mod.sys command
- argument line in the config.sys and use the "OPEN"
- parameter for lansup.com in the net.cfg. -or- (2) Set
- "o=y" in dxmt0mod.sys command line allowing
- dxmt0mod.sys to open the adapter and set the frame
- size, and exclude lansup.com's "OPEN" parameter from the
-
- net.cfg.
-
- Use the following net.cfg syntax when using "OPEN":
-
- LINK DRIVER LANSUP
- OPEN
- <add other parameters as needed>
-
-
- 9/14/92: Lansup.com has been updated to be compatible with
- DXME0MOD.sys from IBM Lan Support program v1.30.
- Token.com has also been updated to work with Odinsup.com
- where DXME0MOD.SYS V1.30 is involved.
