I thought this was particularly dependent on the BIOS to support AHCI,
and not necessarily so much on SES alone?

Many desktop grade motherboard can hot swap a SATA HDD and they don't
have SES, only AHCI in the BIOS. Or is HP just trying to stay on the
safe side with not advertising hot swap, incase someone with Windows
has issues with it?
