It doesn't shows up under /proc/ide/ide/ide0/hda (with ide-scsi driver), and in /proc/scsi/scsi. Then I tried the 2.6 kernel on Knoppix 3.7, and it didn't work either. It hung during startup, the screen showing: ... ide: Assuming 33Mhz ... hda: SAMSUNG CD_ROM SN-124, ATAPI CD/DVD-ROM drive ide1: I/O resource 0x170-0x177 not free. ide1: ports already in use, skipping probe ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 ata_piix: combined mode detected ACPI: ... ata: 0x1f0 IDE port busy ... Enabling DMA acceleration for: hda [SAMSUNG CD_ROM SN-124] Accessing KNOPPIX CDROM at /dev/scd0... And it just stayed there. Tried with the nodma option (boot: knoppix26 nodma), and it was exactly the same except the "Enabling DMA ..." line didn't show up. >>*** IPv6 problem >> >> >Any details about what exactly breaks?

Apparently bind would try some queries over IPv6 which would not work since it's an IPv4 network. I cannot remember the exact details. The related messages I find on the web mostly talk about Mozilla / Firefox being slow. But I experienced problems while only trying "host" or "dig". It is not Debian-specific since I find people recommending the same fix for Fedora Core, Ubuntu, Mandrake, Suse, etc. So it looks like a generic problem with IPv6 enabled on non-IPv6 networks. Maybe Sarge could be the first distribution to fix that annoying glitch... :-) A few links to that problem: http://miro.larts.co.uk/blog/index.php?title=redhat_fedora_6_and_ipv6&more=1&c=1&tb=1&pb=1 http://portal.suse.de/sdb/en/2003/10/90_mozilla_ipv6.html http://ubuntuforums.org/showthread.php?t=171 http://ubuntuforums.org/archive/index.php/t-6841.html And a lengthy thread on bugzilla that seems to be related: https://bugzilla.mozilla.org/show_bug.cgi?id=239358 Anyway, disabling IPv6 fixed it. Does it make sense to enable IPv6 by default? >This is supported. The automatic partitioning just sets up a proposed >partition table and then lets you accept it unchanged, or edit it.

You can not resize the 2nd and 3d partitions while leaving the 4th and 5th as they are. cfdisk or fdisk don't support that either. Then there is the problem with the excessive number of dialogs to assign mount points: 2 (or 3?) dialog boxes for every single partition. That's a lot clicking or Tab-bing around. I'm sure this could be streamlined into a simpler screen, but I do realize it isn't easy since the standard partitionning utilities don't support resizing either, and there are potentially many options for mount points.
