Next old system that I decided to have a look at is the Digital UNIX (Alpha) predecessor of Tru64 UNIX.
For my test I have used the ISO available from here : https://winworldpc.com/product/digital-unix/40e
This version is supposed to be supported by alphavm_free so I have decide to try it out. Here are my experiment logs.
My network script for alphavm_free is such :
#Setup tap and bridge tunctl -t tap0 -u user ifconfig tap0 up brctl addbr br0 brctl addif br0 eth0 brctl setfd br0 0 ifconfig eth0 10.0.2.1 up ifconfig br0 10.0.2.2 netmask 255.255.255.0 broadcast 10.0.2.255 up brctl addif br0 tap0 ifconfig tap0 0.0.0.0 sysctl net.ipv4.ip_forward=1 iptables -A FORWARD --in-interface eth0 -j ACCEPT iptables --table nat -A POSTROUTING --out-interface wlan0 -j MASQUERADE
Following is the semi-working config.emu file (using the Alpha ds20l)
config.emu
system {
type = ds20l_833;
reported_type = default;
num_cpus = 1;
ssn = 'EmuVM-00-000-001';
interval_clock_freq = 100;
memory {
size = 512;
}
cpu {
server = basic;
jit {
async = yes;
}
}
serial com1 {
server = socket;
port = 3000;
}
scsi_controller qla0 {
}
scsi_controller qla1 {
}
scsi_disk dka0 {
scsi_bus = 0;
scsi_id = 0;
scsi_lun = 0;
file = 'disk.dd';
caching = no;
write_through = yes;
}
scsi_cdrom iso {
scsi_id = 4 ;
file = 'digital.unix.4.0e.iso';
}
ether eth0 {
type = dec21040;
server = dummy;
mac_address = 0x08002B000001;
}
ether eth1 {
type = dec21040;
server = tap;
interface = 'tap0';
mac_address = 0x08002B000002;
}
}
Standard environment (dka0 as disk.dd and dka400 iso cdrom)
disk.dd created as
dd if=/dev/zero of=disk.dd bs=1024 count=2M
Boot alphavm_free as
./alphavm_free config.emu
Boot the CDROM ISO
>>>> boot dka400
And you end up with this

Hmmm… something that the installer script does not like about the disks .. lets check the disk info form the shell we get
# scu show edt CAM Equipment Device Table (EDT) Information: Device: HD image Bus: 0, Target: 0, Lun: 0, Type: Direct Access Device: CDROM ISO image Bus: 0, Target: 4, Lun: 0, Type: Read-Only Direct Access
OK so the system sees our disk.dd image as HD image
Checking the /dev for presence of dk0
no rrz0* entries in /dev , so lets create them
# cd /dev # ./MAKEDEV rz0
Now /dev has the rz0 entries as
So we re-run the CDROM installation script, it is sitting in the
# ls -la /isl/.profile -rwxr-xr-x 1 bin bin 39619 Nov 13 20:22 /isl/.profile

Same error… digging deeper .. From the .profile script we can see that the local disk gets discovered by the finder command
PrepInst()

# Determine whether this is a lite system or not.
LITEFLAG=`sizer -l` # lite = 1
# Invoke discovery phase of finder so the delay to get disk
# information to the UI is minimized. Setld discovery is delayed

I will try to figure out why the disks dont get detected, as I see some great potential in setting up this system :)
