It would be nice if you business partners would read what you are dropping here. Calling me a troll and then using the word "Hundepimmel" in the same mail: Does this guy Eric Furman read what he writes? This is an obvious Dunning-Kruger. Being given offence by a community that doesn't throw out such a low-minded person is not really hurting me. Poor, poor people. I should feel sorry for you but you would have no use for that.

Installer overwrites partition table
Hi, first of all, I am an experienced OS installer and I did a heck of partitioning in my life. Now I had some unused disk space and I found it a good idea to install OpenBSD. The installers partitioning tool didn't offer me a variant that keeps my existing partitions. Therefore I immediately stopped it. But yet it was too late. The partition table was overwritten. The damage is not hard for me because I tersely do backups. But this behaviour is impudent. This blowfish is not a safe operating system, it rather is a poorly prepared fugu.

Hi, Am Montag, 29. Okt 2007, 11:01:44 +0100 schrieb Pau Amaro-Seoane: I don't quite understand what you're doing? Are you looking for a dual-boot with linux via grub? Yes. I have a Linux box here with Grub. Admittedly the first hard disk contains a Windows that gets used sometimes by other persons. What else should I do? Buy another machine while I have unused disk space here? Migrate back to Windows before I try out OpenBSD? If so, have a look at www.aei.mpg.de/~pau/zen_process_obsd.html Read it in detail. If not, just forget this mail. This is exactly what I did. The first difference appears while partitioning. I quote the document you told me I should have a look at: Here is the partition information you chose: Disk: wd0 geometry: 969/128/63 [7814016 Sectors] #: idC H S -C H S [ start: size ] .. *2: A6 304 103 1 - 968 25 63 [ 2457945: 5349645 ] OpenBSD .. ... Treating sectors 2457945-7807590 as the OpenBSD portion of the disk. You can use the 'b' command to change this. When I run the installation this reads: Treating sectors 63-120103200 as the OpenBSD portion of the disk. You can use the 'b' command to change this. Unfortunately, when I use the 'b' command, this won't change. The partition table is written to sector 1. Not 63. Not 64. Not 6323185. Not 6323186. I not even find a way to display that message again after I changed the portion. The document you pointed to doesn't mention a command to display what the portion is. I tried it several times. I booted the CD, ran disklabel/install/..., booted linux, dd|od'ed the sectors (there's no od on the CD), re-booted the CD, ... Yes, I do read documentation and I read it in detail. I still will be glad if you point me to some new information. Telling me to read again and again the same doesn't make the disklabel command behave different. Please do you read the reports I post in detail. Bertram 2007/10/29, Bertram Scharpf [EMAIL PROTECTED]: Hi again, Am Montag, 29.

This is not supported. Reallocated your fdisk partitions so the OpenBSD partition is a primary partition and reinstall (you may have to resize your extended partition, ID=5, to make room). Those @#$! extended partitions! It's really time for me to get rid of that kind of programming style. I tried it out on another machine where I had a free primary partition. Hoolay--it boots!
