What is ata2 ?

[Rob]

Hi,

I'm running FreeBSD on a range of PCs, from Pentium-1
(60 MHz) to Pentium-4 (2.60GHz), though none but one
has a 'ata2' line in the dmesg output:

 ata0: channel #0 on atapci0
 ata1: channel #1 on atapci0
 ...
 ata2: <Generic ESDI/IDE/ATA controller> at port
       0x36e-0x36f,0x168-0x16f irq 10 on isa0
 ad0: 6149MB <QUANTUM FIREBALL EX6.4A/A0A.0D00>
      [13328/15/63] at ata0-master UDMA33
 ad1: 4892MB <QUANTUM FIREBALL EL5.1A/A08.1100>
      [10602/15/63] at ata0-slave UDMA33
 acd0: CDROM <GCR-8521B/1.02> at ata1-master PIO4

What is so special about this particular PC, that it
has an ata2, unlike all other PCs I have?

Can I add more than 4 disks (2 masters + 2 slaves)
to this PC? Or is this ata2 for something else?

This particular PC is running 5-Stable.

Thanks,
Rob.
