William, the boottracks used on those disks point to the VHD for their OS9Boot file (boot_becker). The only thing used from the HDBDOS disk image (disk 200) IS the boottrack. The "boot_becker"n will always look to DW drive 0 (OS9 partition).
Try Copying the OS9Boot file (not the kernel) from the disk you created to the VHD.
It's a common mistake when using boots for HDs and such. The way it works is the "boot" file used in the boottrack (in L1, Rel, krn, krnp2, init, & boot) determines on what device rel looks for the OS9Boot. The boot I used on the XRoar Starter Kits is the "boot_becker" which looks to the VHD0, not the floppy which holds the boottrack. A standard floppy boot could be used and then it would boot from the intended floppy image on the HDBDOS drive.
I hope this makes sense.

Feel free to email me off list anytime :-)

I hate to be a bother Bill but I cannot figure out how to get my ownOS9Boot to be recognized by the system.  The same procedure I use for VCCis not working.Here is what I am doing:Insert a 35 track single sided disk image into Xroar Drive 1 making sure itis writableCreate my 35 track single sided boot disk in /d0Hard reset XRoar.Press 6 to exit to BASICMake sure that drives 1-4 are turned off.  DRIVE OFF(Do a DIR 0 to make sure the disk image is seen)BACKUP 0 TO 200 ( I know that 255 is supposed to be the currently linkeddrive because the program listing for the AUTOEXEC.BAS does a DOS 255command when you press '5' to boot NitrOS-9)DRIVE 254 (Where the HDB-DOS tools reside)NEW:RUN"LINK.BAS"When prompted what drive to link to I type '200'.Hard reset XRoarPress 6 to exit to BASICDOS 200NitrOS-9 boots and I do a 'mdir" command. It's not my OS9Boot that hasloaded.  It's still the default OS9Boot.I have tried backing up to drive 255 and booting both with and withoutrunning the LINK.BAS program.Deleting the OS9Boot from the DriveWire drive /x0 and replacing it with myOS9Boot makes NitrOS-9 crash before the version information is displayed.Deleting my OS9Boot and replacing it with the original OS9Boot also causesNitrOS-9 to crash before the version information is displayed.  Is there adocumented procedure for creating you own OS9Boot?Thanks,William Carlin-- Coco mailing listCoco at maltedmedia.comhttps://pairlist5.pair.net/mailman/listinfo/coco
