OpenVMS bootable CD in ram

I used the following sequence to generate an openvms bootable cd.
But it dos not work:

$ld create /log /size=1331200 bootable2.dsk
$SET FILE/ATTRIBUT=(LRL:512) bootable2.dsk
$initialize /system /share /erase /cluster=4 LDA1: BOOTABLE
$ld connect bootable2.dsk LDA1:
$mount LDA1: bootable
$ @SYS$SYSTEM:AXPVMS$PCSI_INSTALL_MIN.COM
Enter device name for target disk: (? for choices) LDA1:
$ run sys$system:sysman
SYSMAN> parameters use lda1:[syse.sysexe]alphavmssys.par
SYSMAN> parameters show wlksysdsk
SYSMAN> parameters set wlksysdsk 1
SYSMAN> parameters write lda1:[syse.sysexe]alphavmssys.par
SYSMAN> exit
$ SET FILE/ENTER=LDA1:[000000]SYS0.DIR LDA1:[000000]SYSE.DIR
$ RUN SYS$SYSTEM:WRITEBOOT
Update VAX portion of boot block (default is Y) : n
Update AXP portion of boot block (default is Y) :
Enter AXP boot file : LDA1:[SYS0.SYSCOMMON.SYSEXE]APB.EXE;1
$ LD PROTECT LDA1:
$ DISMOUNT LDA1:
$ LD DISCONNECT LDA1:
set file /attribut=(LRL:512) bootable2.dsk

after the ftp transfert I burn the cd as an external image with nero ( 2048 blocks )

I try to boot from the cd and it doe not work:

I don't know what to do and doe not see the mistake I have done.
Someone can help me....

Thanks

Re: OpenVMS bootable CD in ram

Your commands appear ok.
What happens when you boot from the CD?

Re: OpenVMS bootable CD in ram

If I understand the gist of this, you are trying to build a bootable image (including writebooting it) into a logical drive (LD) and then burn that to CD. Won't what writeboot wants to do on an LD vs a CD be different?

Re: OpenVMS bootable CD in ram

Emmanuel,

I just created a CD using the commands you gave (swapping the LD CONNECT and the INITIALIZE), and it worked!

Environment: AlphaStation 200 with OpenVMS 7.3-2, Windows PC with Nero Express.

Re: OpenVMS bootable CD in ram

Emmanuel,

Is your CD bootable? No all CDs on alphas are bootable. Try to boot from the standard OpenVMS distribution CD.

Re: OpenVMS bootable CD in ram

What Bojan probably meant to say is that not all CD-ROM drives (most notably IDE drives) are bootable on all Alphas (most notably some PWS).

So, if you _can_ boot the VMS OS CD, something else must have gone wrong.

It would certainly help if you could be a little more specific in exactly *what* didn't work.

Re: OpenVMS bootable CD in ram

It looks that you did everything OK.
I had a strange problem once. I created CD ISO image using DFY$VMSCD utility and transfered it to PC by ftp.
I burned it with Alcohol 120% and it did not work. Then I burned the same image with CloneCD and it worked. You should try to burn CD using another program or different version of Nero.

Re: OpenVMS bootable CD in ram

Maurille,

I have no first hand experience with creating bootable CD's, but I see one error in your procedure:

$initialize /system /share /erase /cluster=4 LDA1: BOOTABLE
$ld connect bootable2.dsk LDA1:

should be:

$ld connect bootable2.dsk LDA1:
$initialize /system /share /erase /cluster=4 LDA1: BOOTABLE

You must connect (i.e. create) the LD device before you can initialize it.

But I suppose you did it in the right order already.

Re: OpenVMS bootable CD in ram

Hi,

as a first step, did you try to MOUNT the CD ? And then use ANAL/DISK. If that won't work, you don't even need to try a boot.

Re: OpenVMS bootable CD in ram

Hye,
The probleme comes from the console port I used. It ws the console port 2. As i understand it has not the same right of the conlsole port number 1. This is the reason why all the trace do not appear on the screen.

The cd is bottable anyway.

Thanks for all your answer.
