To answer your questions:

1) I’m running Ubuntu Gutsy Gibbon release, which according to my dhcpd.conf file is running ‘ISC dhcpd’

My dhcpd.conf file looks like this:

====== dhcpd.conf =====
ddns-update-style none;
default-lease-time 600;
max-lease-time 7200;
log-facility local7;

option grubmenu code 150 = text;

subnet 192.168.1.0 netmask 255.255.255.0 {
}

host laptop {
hardware ethernet 00:00:00:60:B6:68;
option grubmenu “/boot/grub/menu.lst”;
fixed-address 192.168.1.34;
option subnet-mask 255.255.255.0;
option routers 192.168.1.10;
next-server 192.168.1.20;
filename “/boot/grub/pxegrub”;
}

===== end dhcpd.conf ====

2) I didn’t need to manually enter anything under grub, it was all configured from the /boot/grub/menu.lst file.

When I was reading up about this I noted that some people under red hat were having issues with the default tftpd server. I’ll see if I can dig up the answer they came up with.

After adding cutom option:
option grubmenu code 150 = text;
option grubmenu “/boot/grub/menu.lst”;
into /etc/dhcpd.conf
The dhcpd server does not start at all.
on Scientific Linux 5.1, on debian/etch and
CentOS 5.1.
What Operating system you use for DHCP server?
You didn’t mention it in your blog.

I managed to get into command line pxegrub only without the custom options from dhcp server.

If I manually enter
kernel$ /solaris/platform/i86pc/kernel/$ISADIR/unix -m verbose -B install_server=[ip of your nfs server]:/export/opensolaris/
It works
If I manually enter
module /solaris/x86.microroot
it start reading the file. I see 20 dots. and then I get:
Disk read error

Do you have any idea how to resolve both issues?
