For what it's worth, I agree 100% with your conclusions below. LBA48 IS NOT GUARANTEED to function reliably without a proper drive, controller, and kernel. Additionally, if you want to boot in LBA48 mode you need a bootable LBA48 IDE controller and/or suitable BIOS.
I think we have settled this issue once and for all. --- Meelis Roos <[EMAIL PROTECTED]> wrote: <SNIP> > MJT> http://www.ussg.iu.edu/hypermail/linux/kernel/0204.3/0484.html > MJT> > MJT> According to it, you should be able to use the drives in your > MJT> U10, but not boot from them (the kernel doesn't use the PROM > MJT> after the boot process and most modern kernels support LBA48). > > That's not so simple. > </SNIP> <SNIP> > For U5/U10 the problem lies in the IDE controller - the integrated > controller does not support LBA48 in DMA mode.
