Thanks Dandy.
I actually was thinking about you last night when reading the details of the Hard Drive Manual( Bridgeboard section)..
I think your comment earlier was correct.
You might be 100% correct in your statement that "you can't Autoboot PC Bridgeboard side".
I am still testing, but I think I stumbled on a Modern Technology solution with the ISA/IDE Adapter (MS DOS boot).
It would have not been possible in 1990 (no Lotech Adapter).
So the Miracle solution I stumbled upon is thanks to Pat for suggesting to me getting a Lotech ISA/IDE Adapter.
I think my DOS Boots off the SD card only works because the Lotech Adapter doesn't work on power up.
It tricks the Amiga to think no Hard drive at power up, so leaves Autoboot enabled.
Then a 8086 reset (thru Icon, or CTRL-ALT-Delete), activates the Lotech-HardDrive, then reboots PC via AutoBoot[enabled].. ( with emtpy Aboot.cnfg file).
If the lotech adapter initialized on power up my 8086, I would have to rebooted PC with a Floppy.
What this means is I'll never be able to boot 8086-BB-PC off the Western Digital/RLL Drive (because it picks up on power up)
---> I was thinking a trick solution (Have a mechanical power ON/OFF-switch to RLL drive. So during power up, no RLL drive. Then turn on RLL drive after power up to enable Autoboot)
Not a problem, SD card is way better.
I will find out soon with more testing.
If JANUS doesn't pick up the hard drive Amiga Parition on Power up (Lotech), so I'll never be able to create a working Amiga Partition off the 8086 Hard drive. I can't CTRL-ALT-DELETE to re-initialize JANUS.library load (but there may be trick, a script to run DJmount later, but I think Janus.library load is key...We'll see)
IS THERE ARE WAY to LOAD "Expansion folder" (Janus.library driver) after Workbench starts up? I think dynamic is not possible.
I think my choice will be One or the other, never both (Amiga & PC Hard drives together, on ONE-HARD-DRIVE).
Unless I find a another trick. [like the power switch I mentioned above]
Which bring me to an IDEA. I am installing the Aurdiuno controller for the Gotek Display.
With a Relay I could automatically delay the power up of RLL drive, or SD card adapter. (FUture project)
Yes, a Hard drive in Zorro II slot and Hard drive in ISA slot would work to solve both. (Maybe).
--> But I don't have an Amiga Hard drive.
--> TOO BAD THERE IS NO LO-Tech-[ZorroII/IDE] Adapter. (That would be Awesome). I guess the Vampire-II is that, plus more.
