You mention that you have a 30Gb HDD...I am presuming that this is a replacement, hence the need to load the OS using the Floppy Emulator. Is that correct?
If so, do you still have the original HDD with the OS installed on it? If you do, I would try booting from that to see if the hardware is functional. If we can get the desk to boot from the original HDD then we can eliminate a lot of variables, which hopefully will help us figure out what is going wrong with loading the OS.
You may need to go into the BIOS and temporarily force it to boot from the HDD...there is a possiblity that booting from the emulator itself is causing the problem (I had an old PC that had to be expicitly set to boot from the HDD...if it tried to boot from the floppy with no disk inserted it would not move on to then boot from the HDD). In fact, I'd probably completly disconnect the Floppy emulator whilst trying to boot from the HDD
Another option could be to download the full HDD image (I seem to recall that someone posted a link on this forum to an image that they had made for the D8B) and load that image on to your HDD.
Another possibility would be to go the Compact Flash card route, again, there are numerous discusssions on this forum about that process, but this
database entry summarises the process well.
I have also got an old 166MHz base unit which I am booting from a solid state disk, I cannot recall whether I imaged the original drive or downloaded an image from the forum and used that....either way it works well.
Hope that helps and keep us posted!
