Norton Ghost could do it

https://en.m.wikipedia.org/wiki/Ghost_(disk_utility)

Acronis True Image can do this in version 8.0.

You boot from the CD, then select a network destination, and it will clone the hard drive contents there.

There's plenty of ways...

I've recently imaged an HDD using Disk Editor from Norton Utilities, writing it all to a file located on a Samba share, mapped in DOS using Microsoft Network Client 3.0.

On later machines, where it's possible to boot a live-CD Linux, it's as simple as:
smbmount (...) /mnt/remoteshare (NFS also works)
cat /dev/hda > /mnt/remoteshare/filename.img

Linux dd and netcat will do the thing.

Server: nc -l 9000 | dd of=disk.img

Boot an old version of linux on the old computer, preferably something like a stiffy based router distro like freesco. Configure the network card.

Client: dd if=/dev/hda | nc 192.168.what.ever 9000

You can also try an older version of g4u

I suppose you have a dx2-33, how much ram installed?

It has 4MB of total memory

Maybe the 1.1.7 release would work.
Or the tomsrtbt boot floppy with netcat and dd as written by st31276a above.

Dolly in dos will work but you'll need to set a network share.

I was mistaken about having an ISA network card. Dug throughout storage room to no avail. I may end up using a USB null modem with my laptop to do the transfer.

A usb to ide converter is a very handy thing to have on hand. I found mine in a bargain bin a decade or so ago for next to nothing. It makes it very simple to prepare ide drives for old systems on modern systems, as well as imaging them for backup.
