Syslinux - Jan 2002 - Kernel boot problem using PXELinux boot

I used pxelinux.0 to boot my kernel, then the kernel began to boot. However, it
cannot mount nfs root. I checked the nfs root
is exported OK!
The last screen is as followed:

serial sub-system self-test: passed.
internal registers self-test: passed.
ROM checksum self-test: passed (0x04f4518b).

Error 101 is ENOTUNREACH, which implies you don't have the proper 
netmask or gateway setup; so it's probably a DHCP configuration problem.

Note to everyone: I recommend using the kernel's own DHCP service, and 
*NOT* using IPAPPEND in most cases.  The IPAPPEND option is supported 
because of some DHCP configurations where that would obtain two 
different IP addresses.
