DHCP options statement - uint8

I'm attempting to setup a dhcp server in Linux for a specific purpose. I'm following a guide written for Windows and think I am on the right path but need a little guidance.

The document has me creating a vendor class and adding options codes 141, 151, and 163 to supply the clients with a server (ip address), config file (string), and download protocol (byte).

Let me know what you think about mirroring this document with this type of config:

option server code 141 = ip-address;
option config code 151 = text;
option proto  code 163 = uint8;

subnet netmask {
  option server;
  option config "config.cfg";
  option proto 1;

According to the dhcpd.conf and dhcp-options man pages I've found online, this should work. When loading dhcpd, however, I receive a notice the config file is not correctly setup.

option proto code 163 = uint8;
configuration file errors encountered -- exiting
Does anyone have an idea why this data format is not working for me? I am running Slackware 13.37 and ISC-DHCP 4.2.1-P1.

#option proto  code 163 = uint8;
option proto  code 163 = unsigned integer 8;
At the very top of the man page for dhcp-options it accurately lists the other format definitions (ip-address, ip6-address, text, string, etc.) along with [u]int8, [u]int16, [u]int32. The details are spelled out further down which I had not seen until I was actually to the point of grepping through the source to see if I could find what was expected.

If anyone has experience with DHCP and can provide sage advise regarding the 'translation' of my instructions from Windows to Linux I would appreciate it.
