The start sectors are aligned to be %8 clean and the to the cylinder boundary. So far I did not had any trouble with that setup on 4G SD cards (did not try on 8G cards though). For MLO loading I think only the start address might matter... not sure Aligning to 8 sectors is not going to help at all, that is much smaller than the normal erase block size (4MB) and also smaller

Using the regular geometry (255/63/1024), that will never be cylinder aligned, which is ok. Don't try to do cylinder alignment. Hrm - does that also have any implications on not being able to boot from the beagleboard? :)
I tried the beagle image of today and it does not help. fdisk output: (only the end of 2nd partition seems to have moved and is no more Linux LVM type but Linux type) *********************************************************** Disk /dev/sdb: 3941 MB, 3941597184 bytes 122 heads, 62 sectors/track, 1017 cylinders, total 7698432 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x929ea0a6 Device Boot Start End Blocks Id System /dev/sdb1 * 2048 309247 153600 83 Linux /dev/sdb2 309248 1368063 529408 83 Linux ***********************************************************
I only know of one bug on beagleboard where an old xloader requires the boot partition to start at sector 63 independent of the geometry. It is well possible that there are other bugs though. Which x-loader is currently used for openSUSE?
