AHCDEMO Device Testing Program

AHCDEMO - AHC Demonstration

The full version of AHCDEMO is now FREE. See below.

Note: Now that AHCI and SATA are stable interfaces it is unlikely there will be any major updates to this program in the future. Except for a few minor updates the most recent updates to this program happened several years ago.

Brief description: A program to assemble and execute any ATA or ATAPI command on a SATA device attached to an AHCI host controller.. The free/demo version supports only interactive operation. The commercial/full version supports interactive and script files and many additional functions. AHCDEMO uses the AHCIDRVR to perform the actual low level AHCI/SATA/ATA I/O functions.

Here is a partial list of the functions supported by AHCDEMO:

• All ATA/SATA command protocols (NonData, PIO, DMA, NCQ/FPDMA and ATAPI).
• All ATA/SATA resets (COMRESET, SRST and ATAPI DeviceReset).
• CHS, LBA28, LBA48 and ATAPI LBA32 sector addressing.
• Direct support for many ATA commands: Power, SMART, GPL, SET FEATURES, etc.
• Direct support for many ATAPI commands: Read TOC, R/W 10/12, SSU, Inquiry, etc.
• SATA Paritial and Slumber.
• SATA BIST operations.
• Data generation and data compare.
• Fast repeating of I/O commands.
• Full tracing of all host I/O activities.
• Flexiable logging options.
• Script files supporting IF/ELSE, WHILE loops and subroutines (CALL/RETURN).
• Global and local 64-bit variables and C style expressions.
• String variables and string operations.
• Built in simple windowing system.
• Built in text editor.
• As you type help for keyboard input.
• Keyboard input and screen output recall.
• Full decoding and display of ATA IDENTIFY data.

Note: If you are testing SATA ATA devices you need AHCDEMO! If you are testing PATA ATA devices you need ATADEMO.

System Requirements: An x86 PCI bus system with at least 1GB of memory, at least one AHCI SATA host controller, a floppy or USB device for booting DOS. Intel AHCI host controllers are recommended [but we would be happy to help you discover why some other brands of AHCI host controllers exhibit a variety of hang and error conditions that are not seen on Intel host controllers.]
