Experimenting some more, I found that EWF doesn't need to be enabled
at all: ETPREP enables it.

I also found out that EWF initialization during FBA doesn't see the
pre-FBA image CD, yet the following lines are present higher up in
FBALOG.TXT:

> 6:15:21 AM - [FBAAddDevInstanceId] IDE\CDROMSONY_CDU4811____________________________PY0A____\4&374899A1&0&0.0.0
> 6:15:27 AM - [FBAAddDevInstanceId] ELTORITO\ELTORITODISKDEVICE\1&2AA0FFE4&0&0000

The example in the docs shows 2 disks detected during ConfigureEWF in
FBALOG, but in my case only one is found.

I can't get into logical disk manager on the target, but I verified
that the CD is accessible by a DIR D: command - the drive is known,
the system knows there's a CD present (i.e. it doesn't say "device not
ready"), but the directory is empty.

In fact, it looks just like it would in standard windows: I don't know
if the ET volume's contents should be visible here or not.

I included the EWF part of FBALOG:
