heloo all

i have got the asus p5b deluxe and i,m having all sorts of problems but anyway, i have an option in the bios that says configure sata as IDE, AHCI and raid.

can someone please tell me the difference between the ahci settings and standard ide and is there any benefits for it.

i just tried changing it to AHCI and windows wouldnt boot keep getting BSOD, so its back to default IDE.

i,m not really intersted in raiding.

Thanks
 
Advanced Host Controller Interface Specification
for Serial ATA
The Advanced Host Controller Interface (AHCI) specification describes the register-level interface for a Host Controller for Serial ATA 1.0a and Serial ATA II. The specification includes a description of the hardware/software interface between system software and the host controller hardware. This specification is intended for hardware component designers, system builders and device driver (software) developers.

Implementation of the Advanced Host Controller Interface Specification requires a license from Intel. Contributors of the Advanced Host Controller Interface Specification for Serial ATA have signed the Advanced Host Controller Interface Specification for Serial ATA - Contributors Agreement in order to be licensed to use and implement this Specification. This Contributors Agreement provides Contributors with a reciprocal, royalty-free license to certain intellectual property rights from Intel and other Contributors for their products that are compliant with the licensed versions of the Advanced Host Controller Interface Specification for Serial ATA.

Intel intends to continue including suitable inputs, comments and suggestions from contributors to refine and update the Advanced Host Controller Interface Specification through a series of specification releases that will be marked as being Revision 1.x of the specification. Licensing of the applicable final specification of the AHCI Specification (As defined in the Contributors Agreement) allows the implementation of both discrete and integrated compliant AHCI host controllers. Licensing of the applicable draft version of the applicable specification level (Also defined in the Contributors Agreement) will allow the implementation of compliant, discrete AHCI host controllers only.

The latest revision of the specification is Revision 1.1. Subsequent Revision 1.x levels of the specification will be completed by Intel at its discretion as time and circumstances permit.


MORE PLAINLY

The Advanced Host Controller Interface (AHCI) is a hardware mechanism that allows software to communicate with Serial ATA devices such as host bus adaptors. The specification details a system memory structure for computer hardware vendors, in order to transfer data between system memory and the device.

The AHCI protocol was announced by Intel in a May 2003 press release.

Note: Enabling AHCI mode in BIOS may cause problems with any already installed Operating System, and may require re-installing the OS. Microsoft Windows requires a separate driver diskette for installation on AHCI-enabled disks, using the F6 Installation method. Failure to do so will spawn a 0x7B BSOD STOP error. Switching to AHCI requires installing new drivers before changing BIOS settings. Some later versions of Windows XP Service Pack 2 include limited AHCI/SATA support

thanks stelly

it doesnt really say the benefits, compare to the ide does it enable ncq, is it quicker.

whats the benefits?

are you using it your self?

AHCI is developed by an industry group chaired by Intel. The AHCI Contributor Group, also consists of AMD, Dell, Marvell, Maxtor, Microsoft, Red Hat, Seagate and StorageGear in addition to Intel.

AHCI provides a standard interface to system driver/OS software for discovering and implementing such advanced SATA features as command queuing, hot plug and power management. AHCI-based platforms improve the performance of the storage sub-system significantly and advances adoption of AHCI-based host bus adaptors (HBAs) and software in the PC platform.

I doubt very much that you will see a difference, I did think about using it but I'm not 100% sure with it at the moment... so I'm leaving it till I know for sure

hi stelly

so another word, this can enable ncq, hit plug and other features.

i'll give it a try

i,m not sure if i have to install it via f6 in wondows xp setup.

you know anything about that, i'll check as well
 
basicaly i,m trying to sort out this weird floppy problem that seems i,m the only one who have it.

have a look at this please

just having silly floppy drives issues, even formatting and writing to it, its so annoying when iuts only the measly floppy drive is causing issues like this.


once you get that error you put a floppy disk in and formats it and than everything works normaly, as soon as you shut the pc or restart it , the error is back.
