IO08718: NETWORK ISSUES WHEN HD BOOTING 4694-347 PMR36220 NSR10391044651

APAR status

• Closed as program error.

Error description

• The customer notices network problems when they boot from the
  harddrive, but when they PXE boot everything is fine.  The did a
  little digging and found the no_cable_magic option is being used
  on the disknetboot image (stage4.sh) and it's not being used on
  the base images.
  

Local fix

• reload natsemi network module with no_cable_magic=1 option.
  

Problem summary

• Network problems are sometimes seen when using the natsemi
  network card on a POS terminal that booted from the hard disk,
  especially if using long ethernet cables.  Adding
  "no_cable_magic=1" to the kernel command line is the fix for
  this issue, but it's not obvious as how to do this.
  

Problem conclusion

• POS terminals that pxe boot use Novell's disknetboot image,
  which is already equipped with the "no_cable_magic" workaround,
  but the final image that is placed on the POS terminals hard
  disk is missing this kernel parameter.  Novell explains how to
  build client images with this kernel option in the following
