Hi all, Something strange here : I installed latest beta sol10 onto an old ZDS system. All went fine exept the "beta-related" problems during use. Afterwards Sol10 3/05 GA released and I installed it but ... Install went ok, but after the reboot, I always need the cd1 to boot from, selecting boot device in the DCA. I've found the x86 boot sequence white paper and found that the Partition Boot Record is the culpritt. I launched installboot pboot bootblk c0d0s0 but afterwards, nothing seems to be changed. Still need the cd to start. Looking forward to your tips and advices, Didier.
