I'm trying to setup Digital Unix 4.0C on FreeAXP and when booting from the Digital Unix CD it always fails to mount the root file system.
My FreeAXP configuration is very simple: only a clean disk image file on DKA100 for the installation and the CD drive on DKA200. I've already tried different alternatives as far as the DKA100 disk file is concerned:

1 - A new 2GB disk image file created with FreeAXP.

2 - A new 1,5 GB disk image of type RZ27 downloaded from the FreeAXP site (empty disk image files available for download).

3 - A new 2GB disk image file created and formatted with disklabel and newfs at a PersonalAlpha emulator that I installed previously with the same Digital Unix version.

With all of them the installation always fails as following:

>>>BOOT DKA200
(boot dka200.2.0.6.0 -flags A)
block 0 of dka200.2.0.6.0 is a valid boot block

I had absolutely no problem in installing the same operating system in Personal Alpha but with FreeAXP it always fails. Can anyone please give me a clue about this?

Thanks in advance.

Hi,

What version of FreeAXP are you experimenting with ?

I notice the boot strings indicate 'Digital UNIX V4.0B (Rev. 564)'. V4.0B is not one we have tested yet, but I'd expect it to work ... However, at this point, I'm wondering if this is a product of an old/older release of FreeAXP ? since we don't see vfs_mountroot panics at all under V3.2C/G or V4.0D/F/G.

Either way, since you have release V4.0B, we would be very interested in obtaining a copy to test with.

regards,
John M

Hi again,

Try setting pka0_disconnect to 0 before you boot :

>>> set pka0_disconnect 0
>>> init
ff.fe.fd.fc.fb.fa.f9.f8.f7.f6.f5.
ef.df.ee.ed.ec.f4.eb.ea.e9.e8.e7.e6.....e5.
V7.0-9, built on Mar 18 1999 at 13:25:37
>>> boot dka200

It ~might~ help.

Hi John,

I'm using the last FreeAXP version (307) and the label on my Digital Unix CD says "DIGITAL UNIX V4.0C" and "Includes DIGITAL UNIX 4.0B" so probably the kernel version is in fact 4.0B.
I'm running FreeAXP on a PC with Windows XP SP2 1GB RAM, but I've also tried in a Windows 2003 server with 3GB RAM and the results were the same.

Interestingly, I followed your suggestion of setting pka0_disconnect to 0 and it still fails but now with a completely new description:

>>>boot dka200

This sounds to errors related with the disks emulation don't you think(it doesn't even display the SCSI devices found)?
When I reset pka0_disconnect to 1 again, it failed with the same error messages I posted the first time.

I have another older Digital Unix V3.2D but with this one the results are even worse:

Can it be a CD problem? I'm going to try to copy them.

Hi again,
I'm wondering if this cannot be a problem with the CDs. I retried several times in different machines and sometimes fails saying:

panic (cpu 0): vfs_mountroot: cannot mount root

and other times fails saying:

cam_logger: CAM_ERROR packet
cam_logger: bus 0 target 2 lun 3
ss_perform_timeout

This later one refers to bus 0 target 2 which is the CD, right?

Anyway, as I was successful installing on PersonalAlpha some time ago, I had the idea of starting up FreeAXP using the PersonalAlpha disk (I read somewhere in the user manual that this would be possible). However now I have a very basic failure: when starting FreeAXP with the PersonalAlpha disk it says that the CPU is different and then halts.
In fact FreeAXP emulates an Alpha Server 400 and PersonalAlpha emulates a DEC3000/400, but according to the user manual FreeAXP would support it. Am I missing something?

It certainly looks like a disk or scsi problem. For now, forget about pka0_disconnect ;-) I think I'll get Bruce to release to you a more recent version as 307 will be replaced very shortly by a new release of FreeAXP anyway.

As to using a PA boot disk, as you say PA emulates a DEC 3000-400, which is quite different from an Alphaserver 400. The former was a turbo-channel system, the later a PCI system. Booting the '/genvmunix' (-file /genvmunix) from your PA build may work ~if~ it is V3.2C or later. The Alphaserver 400 4/166 is only supported by V3.2C upwards.

The V3.2D boot result looks most odd. Clearly the disk is 'visible' :
> block 0 of dka200.2.0.6.0 is a valid boot block
>reading 16 blocks from dka200.2.0.6.0

...but then it can't find to the filesystem's boot program

> can't open osf_boot

Have you got the image DKA200 set to 'cd', or is this the physical device ? If it is the physical CD, is Explorer accessing the device ? or the index service attempting to index it ?, or autorun attempting to examine it ? The older Tru64 CDs are not in any format known to Windows ...

Could you show us your cfg file ?

John M

Hi,
I received Bruce's new version and finally I could successfully install from my Digital Unix CD without any errors and it seems to be working well! THANKS A LOT!

Now I'm going to configure the system and to make more deep tests and I will let you know the final results with this V4.0B version.

Regarding your questions about the problems with the FreeAXP 307, now I know that the CDs are good as the installation with the 345 version was successful - I'm using original DEC CDs in both cases (V4.0B and V3.2D). I will still try to follow your clues about the Windows index service or autorun, because for me this also seems very odd. As a final note, Windows Explorer in fact doesn't show any content from the CDs.

The config file is as follows:

/* -- FreeAXP Config --
-1000
9000
4098
C:\Program Files\FreeAXP\Capela_dka0.img
1

4

1

1

1

-- */

cp = control
{
cp_log = logfile
{
filename = "C:\Program Files\FreeAXP\Capela.log";
}

alpha = alpha
{
memory=128M;
image = "C:\Program Files\FreeAXP\Capela.nvr";
pcibus = dc21071da
{
data = "C:\Program Files\FreeAXP\Capela.toy";
serial0 = i16550
{
s0_tn = telnet
{
port = 9000;
wait = true;
action = """C:\Program Files\FreeAXP\putty.exe"" telnet://localhost:9000";
}
}

pci7 = i82378
{
}

pci6 = symbios
{

disk0.0 = file
{
image = "C:\Program Files\FreeAXP\Capela_dka0.img";
}

cdrom = true;
}
}

}
}
