In order for the NetMAX to recognize it, you must set up the SB1000 driver. This requires configuring Linux's Plug-and-Play (PnP) system. The simple method, which should work for most installations, is to:

• Obtain a "root" shell on your NetMAX. Use "telnet" to log in as an administrator, and then "su".
• Type the following command:

  /sbin/pnpdump -c | /bin/sed -e 's;(CHECK);;' > /etc/isapnp.conf
  

• It is extremely important to check the resulting /etc/isapnp.conf file to make sure that the GIC board has the correct IO 0 BASE, IO 1 BASE, and INT 0 IRQ values. If you have the Microsft Windows drivers installed, then you can use the System Control Panel to determine the correct values for these parameters. Also check this file for conflicting IO and IRQ parameters regarding other devices that the PnP setup software ma have found.
  
  
• Type the following command:

  echo "sb1000" >> /etc/netmods.list
  

  (note that there are two ">" characters)
  
  
• Reboot your NetMAX for the changes to take effect.

After setting up the dial-out modem, visit the Home -> Network -> Routing page and set the Default Router to the dial-out modem you just configured (ttyS#).

Then visit the Home -> Network -> DNS page and set the Allowed to use InterNIC checkbox, so your NetMAX can resolve names on the Internet.

Lastly, Commit all of these changes.

The next time your NetMAX needs to access the Internet, it should automatically dial your Cable service provider.

RAM

It will ask you if the amount of memory you currently have is correct. Answer n, and it will ask you how much you really have.

You'll have to reboot to get the OS to pick up the changes.

We have found that Linux has a problem finding the memory in some hardware configurations.

Also, you can specify how much memory you have at the Linux boot prompt. When you reboot your NetMAX machine, you should get the Linux boot prompt for 30 seconds at the console. At this prompt type:

linux mem=###M

Where ### is the amount of memory in megabytes. For example, if you have 128M of memory, and the machine is only recognizing 64M, you would type:

linux mem=128M

You would add this line to the /etc/conf.modules file:
options eepro100 max_interrupt_work=40
The variable 40 is just an example, max_interrupt_work uses 20 by defaults. The variable should be determined on a case by case basis.

Note: If you use a number which is to high it potentially could slow down your network traffic.

However, there is a way to add an IDE tape drive from the command line. Here are the instructions:

1. Add the line "insmod ide-tape" (without the quotes) to the /etc/rc.d/rc.local file.
2. Add the tape entry in the /etc/devs.conf file.

   An example is given in the file for reference:

   #[TapeDrive]
   #st0=SCSI Tape 1 <-sample scsi drive line
   

   A sample of what you might enter:

   [TapeDrive]
   ht0=IDE Tape 1
   

3. Reboot or run /usr/netmax/etc/rc.d/Devs.first (for 3.x products) or /etc/init.d/netmax_devs (for 4.x products)

You should now see the drive in the interface, under backup devices.

NOTE: This is for reference only as we can only support the interface. Any command line instructions are done at your own risk.

NetMAX can be installed on a hardware level RAID if:

1. The hardware level RAID is transparent to the OS (operating system).
2. The RAID controller appears to the OS as one of the supported SCSI cards.
3. The RAID controller shows the system drives to the OS with the standard sdX naming schemre.

Most hardware level RAID systems come with a DOS bootable floppy that you use to manage the hardware level RAID, and then you install the OS on the "system" drives that you have created.

It is probably much easier to install NetMAX on a supported SCSI adapter, install the SCSI drivers (and management software if available) for your RAID adapter, and then mount and use the RAID as additional filespace/volumes.

The following messages are usually caused by an Intel Ethernet Express Pro 100 card sharing an IRQ with other devices:

eth0: card reports no RX buffers.
eth0: card reports no resources.

If you have one of these cards and this problem exists you will need to go through the BIOS to force this card to use a unique IRQ.

If you have two of these cards installed and this problem exists try replacing one of the cards with another NIC (check our compatibility list.) If this does not work make sure that this card is using unique IRQ through your BIOS. For more assistance, refer to the manual included with the network card, or to the manufacturer's website.

1. Log in to the NetMAX Interface as the administrative user.
2. In the Files Manager, navigate to the /usr/netmax/etc/rc.d directory. Click on root to begin navigating there.
3. Remove the Devs.first file by placing a check in the box, clicking on Actions, and choosing to "Delete" the file.
