You probably don't have to do this, unless you are running a very old version
of EMC. Any of the BDI CDROMs should not need this.

If you are running the one based on Red Hat 5.2, then there is a line added to one
of the boot sections in the file /etc/lilo.conf, which reads

append="mem=63m"

which means only use 63 megabytes for Linux, reserve the rest.
If you go to 128 Mb, change this line to 127m or so. For 192 Mb, use 190m

Execute LILO with the command

lilo

to install these changes into the boot files on the hard drive.

Then, you have to edit the appropriate xxx.ini file that is called by the xxx.run file you use
to start EMC to have the correct address of this reserved memory area, in hexadecimal.

In the xxx.ini file, there should be lines such as

SHMEM_BASE_ADDRESS = 0xBF00000

that refers to the memory area. 1F00000 is for 32 MB,
3F00000 is for 64 MB,
BF00000 is for 190 MB.

I'm pretty sure this applies only to old versions of EMC, and you don't have to do this anymore.

You need to check the hardware address of the DRO board, and make sure it matches the
specific line in the ini file that informs EMC of this address. You also need to make sure
that no other device is interfering with the DRO board. Reading the pseudofile /proc/ioports
will show all the known I/O addresses that are being used by something within Linux.
You should also check the file /var/log/messages (use tail to just see the last few of them).
Many of the EMC kernel modules write error messages and other diagnostic info there.
