root=/dev/hda5

Note

a) Your root file system may be not on /dev/hda5. Check the correct location and

modify the line " root=/dev/hda5" to match your system configuration. You can

use the " mount" command to see on which device you root file system is

mounted.

b) If your system needs an initial RAM disk image to boot up (especially when

you use a SCSI drive to boot), you should check existing sections in your

lilo.conf file for the " initrd=" line and add it to the new section. The default

RAM disk file name is initrd-2.4.2-2.img for Redhat 7.1, initrd-2.4.7-10.img

for Redhat 7.2.

Tell lilo to boot the new kernel by default by modifying the " default=" line to

" default=linux.hpt37x2" .

After you finish the modification, save the file and exit the editor, then use the

command " lilo" to install the new kernel.

If " lilo" finishes without error, reboot from the new kernel to go to the next step,

" Test the Driver Module" .

Step 3 Test the Driver Module

You can test out the module to ensure that it works for your system by changing

working directory to the location where hpt37x2.o resides and typing in the command

"insmod hpt37x2.o".

Sometimes insmod will report "unresolved symbols" when you attempt to load the

module. This can be caused by two ways:

1) If your system is using a kernel which has not built-in SCSI support, you must load

the SCSI module before load hpt37x2.o. Try to load SCSI modules first.

E.g.

2) If you recompile the kernel with SCSI support and still receive the "unresolved

symbols" error, it may be caused that you have not configured symbol versioning

correctly. To correct it, recompile the kernel with symbol versioning configured. Please

refer to the kernel documents for more information.

To ensure the module has been loaded successfully, you can check the driver status by

typing in the command " cat /proc/scsi/hpt37x2/X" , where X is the filename you found

under /proc/scsi/hpt37x2/. You should see the driver banner and a list of attached drives.

You can now access the drives as a SCSI device (the first device is /dev/sda, then

/dev/sdb, etc.).

# insmod scsi_mod

# insmod sd_mod

# insmod hpt37x2.o
