Qplus embedded Linux system.

Atfer I build all and select to install to target system in the menu Deplpoy Target Image,target system displays that "uncompressing kerenl ...... 0k, booting the kernel"
when i insert the Ethernetboot floppy disk which is maked from the rom-o-matic.org,
then the target system coudn't coutinue ,only the cursor flink .Why?
Though I nearly configure the host like dhcp and tftp service followning fully the user guider ,i couldn't confirm the correct of dhcpd and tftp as my poor linux knowledge.Is it the reason of above phnomenon that dpcpd.conf hasn't been configured. My dhcpd.conf is as belown:

subnet 192.168.1.0 netmask 255.255.255.0 {
# --- default gateway
option routers 192.168.1.254;
option subnet-mask 255.255.255.0;

# we want the nameserver to appear at a fixed address
