I actually got it to install once by disabling the rest of the probes beyond the disk controller. I had a lot of junk (io cards like an eprom burner) so I assumed it was me. I was running an 8003 with irq9 and 0xd0000 memory. My disk controller was an Adaptec 1542B and a 1542CF (tried both). I can't repeat it because my wife blew her motherboard and she's running the Adaptec while I'm running 1.1.5.1-patch22. I should have 2.0.5 up as soon as I get the CD.
