I recently bought a P2B-F that supports ultra DMA 33, but my hard drives are UDMA/66. The place that I bought it from said that it would just be a bios upgrade that would soon be available from ASUS. Is this true? |

Got my answer: was told the MB only supported
UDMA33 and that even with a BIO's upgrade it still
wouldnt support UDMA66 |

As I have a simular problem: I have been told like
you AND have read "dont check the DMA" box and get
a BIO's upgrade.
Am waiting for the answer from the manufacterer of
my MB now & will let you know what they say. |

I think that the sales people might have 'snowed' you. I've requested some information from ASUS regarding your question, although I've not seen any FAQ's regarding the conversion to ATA-66 it doesn't mean that they aren't planning on implementing it at a later date. Of course, implementation of the technology requires that the board physically support the data tranfer rate and I'm not sure if the P2B-F does in it's native revision state. I will send you a reply when I've recieved a response from them. |

UDMA 66 hard drives are all backward compatable with UDMA 33. From what I have heard and read about is that the UDMA 66 is normally turned off by the Harddrive Manuf. And a utility is implemented to enable UDMA 66. UDMA 33 Bios flash to UDMA66 is not likly because of the hardware revisions. You have to either purchase a new motherboard or purchase an addon Card to support UDMA66. |

Most drives come with UDMA 66 turned on, and you need a util to turn them off, Quantum KA, KX, etc.. came this way, as well as many others I have used. I have never actually had to switch any 66 down to 33 or vice versa, they just always worked the way they came.
As far as BIOS upgrading a mainboard from UDMA 33 to 66, forget it. First of all UDMA 33 is IDE to a system bios, but usually the system bios sees the UDMA 66 controller as a SCSI device (even though it isnt) and the UDMA 66 controller then configures the drive independantly of the bios, usually by autodetecting each boot.
Don't forget as well, UDMA 66 requires a different cable!! No my friend, if a salesman told you that a bios upgrade in the future would get you to UDMA 66, than he is in the wrong proffession, please tell his boss and get the slime ball fired.
BTW I have never ever been able to get a responce from ASUS tech support by email. And I have tried quite often. Good luck there. |
