Then why was fdisk -l showing me that the boot volume the installer created as being not aligned properly, and that went away after I manually created it on tty2 with fdisk and popped back to tty1 and continued to the partition step and used the existing partition layout? >> controllers (google to get an idea of just how many).

Well true, I agree that the firmware is old and has problems in that it could more gracefully handle such a situation, but if the table was being aligned the same way it does when I manually fdisk it, I don't think this would be a problem. In fact, I don't think this was ever a problem in the last 10 years I have had it running debian until recently. > It is possible that one of the advanced configuration options of the PERC2 > can instruct it to stop bothering with the MBR, you'll have to test. Ya, don't recall any option like that unfortunately.

Ya, this is what I did end up doing actually (although I partitioned in CLI on installer not live-cd, but same thing no doubt), which is why I can't understand what it is about the installer that changed. >> Anyways, I hope this gets the attention of some of the installer gurus >> out there and possibly point me in the right direction so that this >> can be resolved properly.

So if I understand this right then, it's because when I fdisk, it uses a dos compatible MBR? Then what in the world is partman (right name for sub app?) using? Seemed like it was standard MBR last I looked at fdisk -l, and only differed in that only sda1 was out of alignement. Anyways, I appreciate the reply and some of the insight. Look forward to hearing back from you. Thanks! -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
