Yes. You actually have the choice of booting with aboot or with the 
raw bootloader, as per SRM-howto. On the other hand, the MILO-howto 
says it's possible to boot MILO from SRM, never tried it, though.

I don't think this strictly true with Linux as it is with *BSD or 
Tru64. At least, that's not what sdisklabel tells me. But then again, 
this might be an effect of switching from AlphaBIOS to SRM (much) after 
installing Linux. You certainly have your partition numbers reset, 
because aboot (or MILO) is located at the beginning of the disk 
_before_ the first partition.

While I'm at it, let me mention that I get a floating exception if I 
try to read the disklabel. I run fdisk, then hit (b) and it tells me 
that I have n partitions. If I want to read the label, I get floating 
exception. It is not an effect of having transmogrified the old 
partitioning scheme into a disklabel, as I get the same if I try to 
put a disklabel on a zip, say. sdisklabel is ok.

I think MILO should live before the first partition. I'm not sure 
there is a strict enforcing on partition a starting at the beginning 
of the disk.
