I have the same problem (Thanks Gal!) and since I didn't see an answer
to hpa's question, made tcpdumps. Client is 193.110.157.25, dhcp/tftp-hpa
server is 193.110.157.30.

*ware used:
Intel eepro/100+  (82557/8/9 rev 9, board assembly 748564-005, romchecksum
                   0xdb8681d)

syslinux 1.76-1.i386.rpm
intel boot agent 2.6 build 004
intel undi pxe-2.0 build 071
tftp-hpa-0.30
ISC dhcpd V3.0pl1
