I cannot think of any reason any motherboard manufacturer would do
that. LBA48 support is just part of any reasonably priced chipset they
would buy to implement the PATA support.

For example, the Gigabyte GA-965P-DS3 I got in 2007 uses a JMicron
chipset to support 2 sata ports and a PATA connector which supports 2
PATA devices. The same chipset controls both. If they stripped out
LBA48 for the PATA they'd also be doing it for the SATA. It would not
save them any money. It would actually cost them money to do this
because essentially be "special ordering" a setup like that.

Could you provide details on this PC such as manufacturer and model number?
