Guys, it gets better... I've got a working ISO and can boot to the SYSBOOT> prompt (b/10000001 dua3) from sys1 on the CD but the system Fails to boot further reporting DUA3 (CD/ISO) has been write locked And mount verification is in progress.. I have seen this reported elsewhere for the 7.2 hobbyist kit.. So what's the fix?? How do I boot a vax without a vax (simh) Installation? Do I need to beg a dummy (minimal) system disk file from someone?(DUA0) David David at bitsolve dot com ----------------------------------------------------------------------- My RRD43 reads CDR's fine. BTW, I know it was asked, but not sure if it was answered. I have read VMS install CD's into PC ISO files using Nero, then used them with SIMH to create a VMS system from scratch. I've also read the same discs with Easy CD Creator (don't remember which version) and although the files were slightly different sizes, they still worked fine. I know I gave someone on this forum (was it you, Ethan?) some ISO's... They were made with Easy CD Creator. - Bob -----Original Message----- From: cctalk-admin(a)classiccmp.org [mailto:cctalk-admin@classiccmp.org] On Behalf Of Ethan Dicks Sent: Friday, February 28, 2003 1:38 PM To: cctalk(a)classiccmp.org Subject: RE: Reading a VMS CD-ROM for SIMH under Windows? --- Antonio Carlini <arcarlini(a)iee.org> wrote: I already have verified that my RRD42 does _not_ like CD-R media. :-( -ethan
