if you use the nodhcp boot code, then the dhcp client will not be started on boot. you can put your commands for a static network interface like
ifconfig eth0 192.168.1.2 netmask 255.255.255.0
route add default gw 192.168.1.1
echo "nameserver 192.168.1.1" >> /etc/resolv.conf
into /opt/bootsync.sh and backup that file in /opt/.filetool.lst with the command filetool.sh -b hda1.
if you want to use vmware drives, be sure to use IDE drives, the SCSI ones need drivers from scsi-2.6.33.3-tinycore.tcz. I'm only using IDE drives with vmware since I found no benefit of using the scsi ones besides of more trouble to get them to work
