abort:PIIX3 mothboard's IDE DMA

[hugang]

Hello,everyone ,
	
	I have asus mothboard with a P5/166,32M memory.
	I use kernel 2.2.12-20 form redhat 6.1 ,but the kernel tell me some message
                             	
-----------------------------------------------------------------------
PIIX3: IDE controller on PCI bus 00 dev 39
PIIX3: not 100% native mode: will probe irqs later
    ide1: BM-DMA at 0xe808-0xe80f, BIOS settings: hdc:DMA, hdd:DMA
hdc: IBM-DYKA-22160, ATA DISK drive
hdd: TOSHIBA MK1403MAV, ATA DISK drive
ide1 at 0x170-0x177,0x376 on irq 15
hdc: IBM-DYKA-22160, 2067MB w/90kB Cache, CHS=4200/16/63, (U)DMA
hdd: TOSHIBA MK1403MAV, 1376MB w/128kB Cache, CHS=2796/16/63, DMA
------------------------------------------------------------------------
	
	I did not understand ,The mothboard can suport DMA,why the kernel cant't suport.
Who can help me to fix it.
