from some poor twisted up soul at the opposite end of
the globe:
Hi, Can u please tell me how I can make images of
the Xenix disks? Because I
can't read them with DOS since they have a different
format. I've tried
Winimage and ImageDisk but they didn't work.
I have a lot of these disks, and they are labeled
as:
Games, Development, Updates, Utilities,
Installation.
Well, any kind of advice u could give me will be
very much appreciated
because I'm afraid that if I leave them without
making backup they will get
corrupted in the future. Bye!
I believe he is using the correct drive (he already
booted with these), it crossed my mind. Can't
understand why ID or TD wouldn't work. Please help. Please...

I made images of the Xenix disks I have for my Altos
with ImageDisk and it worked for me.
I don't recall if Xenix has single density tracks, however
it it does, some PC's physically can't read them - I've
also seen some formats which are marginal on some PC's,
slowing the drive slightly can help. Finally, it could be
settings - what is the format of the disk and what type of
drive is he using, and what ImageDisk settings are in
effect.
Unfortunately diskette formats vary widely, and it's not
always an exact science to get a PC to read them ...

Same here with the set that I have--5.25" DSHD 80x2x15x512; nothing
unusual at all about them. I've even copied them to 3.5" DSHD
(keeping the number of sectors per track the same) and installed from
that.
No problems at all.
Cheers,

WHAT size disks?
WHAT machine were they for?
Xenix was available for a lot of different machines, including IBM PC.
But SOME of the machines that it was available for used formats that the
PC FDC can not handle.
For example, wasn't there a Xenix available for the Victor 9000?

As I understand it Altos Xenix (for the 886) at least was quad
density disks. 80 tracks, double density. Should be able to
image them using a 1.2M 5.25" PC floppy as long as software
can understand the format (I'd think it should do it anyway).

Oohhh.. which Altos would this be ? I'm looking
for Xenix
for my Altos 886.
It's a 586 - and unfortunately I don't have a full set of install
media - just a couple of "homemade" disks that I got with
the machine, one of which boots (IIRC).

ImageDisk has no problem reading/writing 80 track DD on
1.2M drives.

I thought the Altos 586 was a Z-80 cpm machine or am I misremembering the
one I had ages ago, kind of a "diamond" shaped case IIRC

The 580 is z80 based, the 586 is 80x86-based. (I think that's an 8086)

Thank you, it was a 580 I had.... I must be developing a bad sector in my

Did ANY OS for the 580 have a "File Allocation Table"?

It would have to have something like one, no?

It's 8086 based and runs Xenix.
Yes, the case looks like a flat diamond from the front (photos on my site).

Altos made a large number of Z80-based machines, not just the 580.
