Please ignore and forgive my obviously unforgivable ignorance: I wanted to test a snapshot of OpenBSD 5.1 on my ThinkPad T500 which runs 5.0 Release. I decided to overwrite the Windows 7 installation which I never use anyway. fdisk(8) before installation was more or less like this:
#: id C H S - C H S [ start: size ] ---------------------------------------------------------------- 0: 07 1 11 5 - 109 59 12 [ 2048: 204800 ] NTFS 1: 07 109 59 13 - 41336 1 2 [ 206848: 77918208 ] NTFS *2: A6 41336 1 3 - 82669 114 10 [ 78125056: 78120960 ] OpenBSD 3: 00 0 0 0 - 0 0 0 [ 0: 0 ] unused During install, when prompted for which partition to use, I selected the run fdisk-option and used the +edit 1; to set partition 1 to type A6, and +flag 1;-command to make it the active and bootable partition like this: #: id C H S - C H S [ start: size ] ---------------------------------------------------------------- 0: 07 1 11 5 - 109 59 12 [ 2048: 204800 ] NTFS *1: A6 109 59 13 - 41336 1 2 [ 206848: 77918208 ] OpenBSD 2: A6 41336 1 3 - 82669 114 10 [ 78125056: 78120960 ] OpenBSD 3: 00 0 0 0 - 0 0 0 [ 0: 0 ] unused I'm almost certain I have done it like this earlier? I mean: just marking the partition to use with +flag n;, upon which the installer used that partition for creating layout with disklabel(8), leaving other partitions untouched? The rest of the installation went well as always with disklabel using the default layout. However, when I wanted to boot into my 5.0 and hence used the +flag 2;-command in fdisk(8), the system still booted into the new 5.1. Now it doesn't matter if I run +flag 1; or +flag 2; -- the system boots into 5.1 anyway. Regards, Erling
