Read ISO CD images

[Wim Van den Wyngaert]

I have downloaded iso cd images.

Is there a way to unpack them without using an empty disk ? On VMS of course ...

Wim

[Ian Miller.]

could you use them as a container file with a pseudo disk driver such as VDDRIVER OR LDDRIVER ?

[Wim Van den Wyngaert]

Ian,

Please some more details. How do you do that ?

Wim,

On VMS >= 7.3-1 you can use the LDDRIVER mentioned by Ian.


First you need to setup the driver, run:
$ @SYS$STARTUP:LD$STARTUP

then you need the LD command. The CLD is embeded in SYS$MANAGER:CDRECORD.COM. You can extract it and do a SET COMMAND or simply run it:
$ @SYS$MANAGER:CDRECORD.COM VERIFY noexist

and give some nonsense ansawers (this is just to get the LD command!)

Now you have the LDA0 device and the LD command. You can do:


$ LD CONNECT isoimage LDA1:
$ MOUNT /OVER=ID LDA1:

Now you have mounted the CD file.

Wim,

The driver LDDRIVER is also present on the freeware CD:

Bojan,

It works. Thx.

The LDdriver supplied with CDRECORD does work with AlphaVMS V7.3

or you can install it from the freeware site

Btw : the command was added without doing an extra @.

Wim,

Probably the command is added with the instalation from the freeware CD. In VMS 7.3-2 the SYS$LDDRIVER is installed with VMS (no need to install anything), but I could not find (realy I havnt put much effort in searching ;) the LD.CLD as a separate file - it is embeded in SYS$MANAGER:CDRECORD.COM.
