What are you trying to do here? This is not in the wiki...

[autoexec]
MOUNT E: NET
E:
SET MTCPCFG=E:\SAMPLE.CFG
NE2000.COM 0x60 10 0x300
DHCP.EXE
IMGMOUNT C hdd.img
IMGMOUNT D Win98.iso
IMGMOUNT A -BOOTCD D

You are meant to boot the C: drive after installation, not load NE2000 drivers or DHCP. If you want networking, use the Win98 networking, don't try to load a DOS network stack.

Just mount the hdd image, and any CD or floppy disk you want, and boot from the C: drive as documented on the wiki.
