I know nothing about Photodesk, but why does it need HardDisc4? Is that
path 'hard-wired' into the application?

As far as I can see, RPCEmu089/439 runs all the applications which
formerly ran on SARPC/439. The hard disc of my SARPC/620 (excepting
!Boot) is mirrored to the HostFS of RPCEmu089/439 so that, if the SARPC
is unwell, I can switch to RPCEmu. This needs about 20GB of storage,
which greatly exceeds the 1GB available in RPCEmu hd4. Moreover, if it
becomes corrupted, RPCEmu hd4 can cause a major problem, since it cannot
then be accessed via RPCEmu, and the only way out is to delete it. On
the other hand, HostFS can be accessed via Windows, allowing it to be
modified, without using RPCEmu.

Why? Here, RPCEmu089/519 (16-Jul-12) works perfectly well, using HostFS
for boot, and storage. BTW it also has networking.

I wouldn't know, but the version here (16-Jul-12) does not have hd4.
