The code is in the oskit: oskit/boot/net/driver.c.

		required_flags = (BOOTP_NET_IP |
				  BOOTP_NET_NETMASK |
				  BOOTP_NET_GATEWAY |
				  BOOTP_NET_HOSTNAME);
		if ((bpi.flags & required_flags) != required_flags) {
#define MISSING(flag, name) if ((bpi.flags & flag) == 0) \
			printf("bootp did not supply %s\n", name)
			MISSING(BOOTP_NET_IP, "my IP address");
			MISSING(BOOTP_NET_NETMASK, "my netmask");
			MISSING(BOOTP_NET_GATEWAY, "gateway address");
			MISSING(BOOTP_NET_HOSTNAME, "my hostname");
#undef	MISSING

It sounds like you're giving it all it wants so maybe you're not
configuring bootp correctly.  Depending on your inclination, you could
check what's happening by running tcpdump or by building your own copy
of netboot and inserting a call to bootp_dump (see oskit/bootp/dump.c).

ps Note that this code obviously generates a slightly different error
from the one you report.  Those lines of code were last updated
30/March/1999 so I suspect either:

1) You're using an old copy of netboot (or OSKit).
2) Perhaps the copies we distribute on the web page are out of date?
   I think we added that page about a year ago so this is quite possible.

Follow-Ups:
