SYNOPSIS:     Token-ring Configuration on Solaris x86 

OS RELEASE:   2.4

PRODUCT:      Solaris x86

KEYWORDS:     token ring configure install


SYMPTOMS:

Token-ring network card is unable to ping other hosts.


DESCRIPTION:

This note is designed to help you avoid addressing conflicts when
configuring the 3Com or IBM 8-bit ISA-bus token-ring adapters. 

Because, most token-ring adapters are set to a base address of CC000,
this default address may conflict with some VGA video cards and may have
to be changed. 


SOLUTION:

Ensure that a ROM address of D2000 and a RAM address of D4000 are used. 
The ROM address range is 8k (D2000-D3FFF) and the shared RAM range
should be set to 16k.  (D4000-D7FFF)

Your approach to this problem is partially dependent on the version of
the operating system you are using.  Therefore, each version will be
addressed separately.  The common element that is independent of
operating system is that you must choose an un-occupied, 24k address
range that lies 8k below a 16k address boundary.  The best address for
most PC's is in the range of 0D2000h through 0D7FFFh.  (The 16k boundary
in this case is address 0D4000.) The shared memory address is also
software selectable via the DOS setup utilities. 


Common configuration:

 8-bit mode                 (SW2, switch 5 on)
 ring speed, 4-16 Mbps      (SW2, switch 4)
 shared RAM size, 16KB      (SW2, switch 2 off, switch 3 on)
 primary, port 0A20-0A23h   (SW2, switch 1 off)
 interrupt 2(9), 3, or 7    (SW1, switches 7 & 8)
 RAM address, 0D4000h, 16k  (set under software control)
 ROM address, 0D2000h, 8k   (SW1, switches 2,4,5 on / 1,3,6
                            off)

Set switches 1 through 6 on switch-block SW1 to address 0D2000 hex.  The
card must be installed in the computer before installing Solaris.
