Raffaelle,
Oh, I wish what you say worked. That would be perfect.
I tried the CTRL-ALT-ESC many time before.
IT DOESN'T do anything.
Maybe part of my Keyboard map problem. But I think not since CTRL works, ESC works and ALT works.
I think that is for higher Bridgeboards 386/486 that were made with newer BIOS. That is why I keep thinking upgrading my Rev 3.5 Bios.
I HAVE A 8086 Bridgeboard, not the 386/486.
** IF SOMEONE HAS A 8088 Bridgeboard and they try CTRL-ALT-ESC at BIOS Boot **
I went to AmigaResource.cx and I checked for Manual PDF file. Manual is common to Bridgeboard 8088 and 80286, and yes!
As you said, from some hints (Chapter 5 page 45, it is stated that 286 "has special Setup Utility".
Unfortunately so it seems that the Setup Utility is available starting from 286 Bridgeboard.
Any more idea's
From the same manual it seems that 8088 card should recognize automatically any hard drive controller xt card inserted into bus slot, so I dunno what is the problem.
I starting supposing that you must do installation with original DOS 3.3 disks provided with Janus XT Board and forget for a certain time the idea of using DOS 6.22.
Once you have setup BB and HD properly then you may think to made all updates to software.
A2088/A2286 Manual is available here:
http://amiga.resource.cx/manual/A2088-A2286.pdfAppendix E (page 71) describes how to instal phisical Hard Drive to PC SIDE.
Somewhere in the manual I also read that installing real PC Hard Disk voids Autoboot from Autoboot PSEUDO Boot Drive into Amiga side. That could be another hint why you failed boot from autoboot virtual disk in your past tests.
It is stated in Appendis B page 58.
As long as it says to use FDISK command provided with Bridgeboard disks I think that this could be a clue to use 3.3 MSDOS Original Disks, and it stated clearly to set the partition as Active.
Maybe something changed from DOS 3.3 to 6.22 in FDisk command that may add some different sequences strings/hex-characters magic numbers in MBR to make an active partition.
