PDC20267: neither IDE port enabled (BIOS)

[Samuel Flory <sflory@xxxxxxxxxxxx>]

  I was trying the ide raid support for the Tyan 2515 /w on board 
promise controller and get this message when booting:

Uniform Multi-Platform E-IDE driver Revision: 6.31
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
PDC20267: IDE controller on PCI bus 00 dev 18
PDC20267: chipset revision 2
PDC20267: not 100% native mode: will probe irqs later
PDC20267: ROM enabled at 0xfeae0000
PDC20267: (U)DMA Burst Bit ENABLED Primary MASTER Mode Secondary MASTER 
Mode.
PDC20267: neither IDE port enabled (BIOS)



  I get this no matter how I confgure the drives in Promise's bios. 
The system works just fine with Promise's ft module.
