OpenVMS bootable CD in ram

[Maurille Emmanuel]

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

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

[Peter Quodling]

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?

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.

Emmanuel,

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

[Martin Vorlaender]

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.

Martin

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.

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.

Bart Zorn

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.
