Due to the problems seen with some motherboards and lba32, it really needs to be possible to specify in a kickstart config that lba32 mode should not be used to avoid ending up with an unbootable machine post-kickstart.
This is being addressed by only putting the lba32 option in if the boot partition ends above the 1024 cyl limit. The installer will not automatically partition a boot partition this high. The user will have to manually make a partition and designate it as the boot partition.
We hope to have a better resolution to this issue in the next release.
Should be better now.
