Re: pxeboot not working for knoppix 7.2.0

[kolrus <thomas@kolrus.eu>]

Hello Ryan,


I think, tg3 module needs ptp - and ptp needs pps - module, which is not
loaded...

One possible workaround solution is:

- Extract miniroot.gz from tftp root dir - maybe /srv/tftp.

    mkdir /root/pxe
    cd /root/pxe
    gunzip -c /srv/tftp/miniroot.gz | cpio -i

   In this dir You will see something like this:

    drwxrwxrwt  2 root   root    4096 Mar 16 20:14 tmp
    drwxr-xr-x 11 root   root   61440 Mar 16 20:14 dev
    drwxr-xr-x  2 root   root    4096 Mar 16 20:14 bin
    drwxr-xr-x  2 root   root    4096 Mar 16 20:14 UNIONFS
    drwxr-xr-x  2 root   root    4096 Mar 16 20:14 sys
    drwxr-xr-x  2 root   root    4096 Mar 16 20:14 ramdisk
    drwxr-xr-x  2 root   root    4096 Mar 16 20:14 mnt-user
    drwxr-xr-x  2 kolrus kolrus  4096 Mar 16 20:14 home
    drwxr-xr-x  3 root   root    4096 Mar 16 20:14 usr
    drwxr-xr-x  2 root   root    4096 Mar 16 20:14 proc
    drwxr-xr-x  4 root   root    4096 Mar 16 20:14 modules
    drwxr-xr-x  2 root   root    4096 Mar 16 20:14 mnt-system
    drwxr-xr-x  2 root   root    4096 Mar 16 20:14 mnt
    drwxr-xr-x  2 root   root    4096 Mar 16 20:14 static
    drwxr-xr-x  2 root   root    4096 Mar 16 20:14 KNOPPIX
    -rwxr-xr-x  1 root   root   38983 Mar 16 20:14 init
    drwxr-xr-x  2 root   root    4096 Mar 16 20:14 etc
    drwxr-xr-x  2 root   root    4096 Mar 16 20:14 sbin
    drwxr-xr-x  3 root   root    4096 Mar 16 20:14 lib

- From booted Knoppix DVD You need to copy
/lib/modules/3.9.6/kernel/drivers/ptp and
/lib/modules/3.9.6/kernel/drivers/pps dirs to modules/drivers/ dir within
dir where miniroot.gz is extracted - /root/pxe/modules/drivers/ in above
example. (You can boot Knoppix DVD on machine where miniroot.gz is
extracted, and then mount file system where miniroot is extracted or boot
Knoppix on other machine with network connection and copy needed dirs with
scp or rsync or use some other possible solution for this...)

- In directory where miniroot.gz is extracted in ./init script file modify
the load_modules()  function by inserting /modules/drivers/*/*.ko into "for
mod in /modules/*.ko /modules/scsi/*.ko; do" line. (Original line is: "for
mod in /modules/*.ko /modules/scsi/*.ko /modules/drivers/*/*.ko; do". New
will be: "for mod in /modules/*.ko /modules/scsi/*.ko
/modules/drivers/*/*.ko; do".)

- Compress the extracted miniroot into new miniroot.gz.

    cd /root/pxe
    find ./ | cpio -H newc -o | gzip -c - > /srv/tftp/miniroot.gz

Thats all. You have a pxe server with new miniroot.gz which is capable to
boot pxe clients with tg3, e1000 and some other network adapters which needs
ptp and pps modules... I think...
