Using mknod to Set Up Device Files
If you only need to change a device le specication, you can use the mknod
command to set up the device le. For example, if you wanted to change the
bus address of your character device le to 6, you could do so by entering the
following:
mknod
/dev/rdsk/6mn c 47 0x0e0600
For a block device, enter:
mknod
/dev/dsk/6s0 b 7 0x0e0600
By convention, the \6" in the device name (/dev/rdsk/6s0 or /dev/dsk/6s0 )
corresponds to the bus address of the device.
Finding the Status of Existing SCSI Bus Addresses
See the procedure at the beginning of this chapter for determining the
addresses of devices currently connected to your system.
Reconfiguring the Kernel
You will need to have two kinds of drivers in the kernel in order to operate the
CD ROM drive: a scsi device driver and a cdfs congurable le system.
Adding the scsi Device Driver
To check for the presence of the scsi device driver, enter the following:
grep scsi /etc/conf/dfile
8
If the display shows one or more lines with scsi, the driver is in place and
active.
If the display shows *scsi, the driver is not active (commented out), and
you will need to edit the dfile to activate the driver.
If the display shows nothing, then you will need to add the scsi device
driver line to dfile by typing the line scsi at the end of the le.
