I have had trouble getting MINIX to boot on my Amstrad 1386, which is
identical to the 2386, I believe, except for the hard drive.  I finally
got MINIX booted today.  I used a program sent me by Roger Wang
(roger@imagen.imagen.com) to copy my 3.5" boot diskettes to 5.25" 1.2M
floppies, boot on an AT-compatible, install MINIX on the hard drive,
and recompile the whole system using Guy Helmer's (uunet!dsuvax!ghelmer)
modified bootblok.  Then I hacked Roger's program to work in reverse,
and copied my new boot disk to a 1.44M floppy.  That booted fine, and
the other 3.5" distribution diskettes seem to work fine.  It seems that
the 720K boot disk distributed by Prentice-Hall just won't work in a lot
of systems with 1.44M boot drives.  The problem is not insurmountable,
though.

Thanks to Guy and Roger, I am now up and running -- almost.  I have a
Seagate ST01 SCSI controller and ST1096n hard drive.  I have to remove
the controller card to get MINIX to boot.  I suspect the ST01 is loading
something into an area of memory that bootblok wants.  Has anyone solved
this problem?

I've been pleased with my Amstrad, and I'm VERY happy now that I have
MINIX running.  I just wish that P-H would distribute a boot disk that
would work on more systems...

Thanks Guy and Roger,

Thank you for your information.
Other recipes were:
- Tell via SETUP that the Drive is 720K
- Copy 720K-Disk to 1.44MB Disk (yes, with 9 Sectors/track on the 1.44MB disk)
