Hi, I'm trying to install cp/m-86 to a virtual machine. I have a bootable floppy image, and I can get it to boot into cp/m, but after I create a cp/m volume (drive b:) it won't let me copy any of the files. I know the floppy image might be a little corrupted (some help texts have random areas that have been transformed into smiley faces and random characters), but I was wondering if PIP is corrupted or if I'm just doing this wrong.
I have B: formatted, ready to have CP/M put on it, so here's the screen:
A>
Now, I type the PIP command so the screen looks like:
A>pip b:=a:*.*
Shouldn't that copy the system to the b: drive? After I press enter, I get:
COPYING -
144BLDR2.CMD
Bdos Err on B: Select
And when I press anything, it goes back to the A> prompt. This happens when I try to copy any file at all. Is it just corrupted?

First: You should use
A> PIP C:=A:*.*
Second: It is essential that you allocate a really small
virtual HD! In VmWare I use a 15.6MB HD and then format
only half of the available cylinders for the CP/M-86 partition,
i.e. ~ 7.8MB. Be sure that you have to allocate at least
10 cyl. and that the whole CP/M-86 partition is less then
8 MB. You can do this - I think you know it - with HDMAINT.
Here the harddisk is B: Later on it will be C:
After formatting the HD you can test it with
A> STAT C:
Hope this helps,
Uwe.

what about reading comp.os.cpm the whole year ?
I already posted my blog entry about installing cp/m-86 in vmware and
virtualbox a few month ago.

I had these same issues, until I changed the partition type
in the master partition table, by mounting the hard disk
image into a Linux VM, and using fdisk. Then HDMAINT
had no problem making the partition, and PIP worked fine,
it seems to STAT as expected, and the programs execute.
I use only VirtualBox for these kind of things (after some
bad experiences with VMware Fusion upgrades breaking
my Linux VMs, so I don't use VMware for anything but my
Windows VMs now).
There's a working set of goods on my web site, here;
http://www.hytherion.com/beattidp/comput/cpm86/
This is CPM-86 booting to a 4MB hard drive -- please feel free
to use it as a working example, and do let me know if somebody
builds a fully-loaded development system (even with GEM etc.).
Note that it was created using the latest version of VirtualBox,
version 4.2.6, running on Mac OS X.
