otr Token-ring driver for Solaris 2.5.1, 2.6 and 7.
Supported adapters:
OC-3136 Olicom Token-Ring PCI 16/4 Adapter
OC-3137 Olicom Token_RIng PCI/II 16/4 Adapter
RF-3140 Olicom RapidFire 3140 Token-Ring 16/4 PCI Adapter
RF-3141 Olicom RapidFire 3141 Token-Ring 16/4 PCI Fiber Adapter
RF-3540 Olicom RapidFire 3540 HSTR 100 PCI Adapter
The driver handles source routing automatically.
Line speeds:
4/16/100 The adapter will auto detect speed on wire.
100 Mbps only with the RF-3540.
Duplex:
TXI/TKP The adapter will auto detect.
Attachment:
STP/UTP
Fiber RF-3141
Frame size:
4472/17.8K When operating in 4 Mbps the maximal (raw) framesize is
4472 bytes. If operating at 16 or 100 Mbps, the maximal
framesize is 17.8K.
Maximal MTU:
As the line speed is not known before open, and applications (as IP) may
request the MTU size before open, we need to setup a default maximal MTU.
This may also adjust the framesize for the source routing field and a
possible snap header.
The maximal MTU is defined in otr.conf. The default is 4420, corresponding
to maximum framesize at 4 Mbps, adjusted for source routing information and
a snap header.
It may be usefull to set the maximal MTU to the largest value possible for
any board and then to reduce this using ifconfig for individual boards.
The driver supports promiscuous mode.
With the driver comes the otrstat utility, giving statistics.
See the otrstat manual page.
Line speed can be forced using the dos setup programs
oct2pcfg for OC-3136, OC-3137
oct3pcfg for RF-3140, RF-3141, RF_3540.
Installation from the otr2733h.pkg file:
pkgadd -d otr2733h.pkg otr
and answer yes when prompted to install the package.
Note for Solaris 2.5.1
The driver may experience problems allocating memory on 2.5.1 systems.
The symptom is a message of the type
<...>: ddi_mem_alloc failed
To overcome this it is necessary to add/change a kernel configuration
parameter. A line with the text
set lomempages=0x80
should be added to the /etc/system file.
The change will then be effective after reboot.
This can be done by writing this command line:
echo >> /etc/system 'set lomempages=0x80'; reboot
and wait for the reboot.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
