Seems like a like a likely candidate but some more digging will be required.

Presumably this is where you were hoping to install from. You could copy the 
sets to an ADFS partition and then tell the installation kernel to pick them 
up from there. The install floppy does contain support for mounting ADFS 
partitions. You could then disable the podule in the bootloader and continue 
with the install. This will get you going until someone figures out the 
problem here.

Thanks for providing the full info. You may also want to use the web site to 
submit a PR for this problem. It helps to make sure that things don't get 
forgotten. The information you have provided here is pretty much everything 
needed for a PR.
