Create a file named /sbin/ifup-local that has a /sbin/modprobe line for your driver name.
For example, if your ATM driver is fore_200e:
[root@oakbank]# cat /sbin/ifup-local /sbin/modprobe fore_200e;
If you are using the he driver for Fore HE 155 cards
[root@oakbank]# cat /sbin/ifup-local /sbin/modprobe he;
Next, make sure the /sbin/ifup-local file is executable.
[root@oakbank]# chmod 755 /sbin/ifup-local
Create a file named /sbin/ifup-pre-local that has a /sbin/modprobe line for your driver name.
For example, if you are using the he driver for Fore HE 155 cards
[root@oakbank]# cat /sbin/ifup-pre-local /sbin/modprobe he;
Next, make sure the /sbin/ifup-pre-local file is executable.
[root@oakbank]# chmod 755 /sbin/ifup-pre-local
During the boot process, your system will attempt to load the ATM driver.
