is no longer 0xA0 or 0xB0. It simply assumes that will never happen. My 500 GB Seagate Barracuda ST3500820AS triggers that corner case on the first init after poweron. The current code hangs forever with my drive. Fix this by rerunning the init sequence after SATA_BAR0+6 is no longer 0xA0 or 0xB0. Add support for SATA port 2-4 (Primary Slave, Secondary Master, Secondary Slave). If only the 2nd SATA port is connected and the hardware acts strangely (contrary to documentation), it will print the error message below and continue anyway. The official AMD asm code behaves the same way. SATA port 0 status = 0 No Primary Master SATA drive on Slot0 SATA port 1 status = 23 0x6=7f, 0x7=7f drive no longer selected after 0 ms, retrying init [8 repetitions] 0x6=7f, 0x7=7f drive no longer selected after 0 ms, retrying init Primary Slave device is not ready after 10 tries Activate and improve debug messages for SPEW log level. Fix some comments. New log messages look like this: PCI: 00:12.0 init sata_bar0=3020 sata_bar1=3060 sata_bar2=3030 sata_bar3=3070 sata_bar4=3000 sata_bar5=fc309000 SATA port 0 status = 23 0x6=a0, 0x7=80 drive detection not yet completed, waiting... 0x6=a0, 0x7=80 drive detection not yet completed, waiting... [... 281 repetitions ...] 0x6=0, 0x7=50 drive no longer selected after 2820 ms, retrying init drive detection done after 0 ms Primary Master device is ready after 2 tries SATA port 1 status = 23 drive detection done after 0 ms Primary Slave device is ready after 1 tries SATA port 2 status = 0 No Secondary Master SATA drive on Slot2 SATA port 3 status = 0 No Secondary Slave SATA drive on Slot3 With this patch, my Asus M2A-VM boots into Linux without problems.

------------------------------------------------------------------------------- Coreboot README ------------------------------------------------------------------------------- Coreboot is a Free Software project aimed at replacing the proprietary BIOS you can find in most of today's computers. It performs just a little bit of hardware initialization and then executes one of many possible payloads, e.g. a Linux kernel. Payloads -------- After the basic initialization of the hardware has been performed, any desired "payload" can be started by coreboot. Examples include: * A Linux kernel * FILO (a simple bootloader with filesystem support) * GRUB2 (a free bootloader; support is in development) * OpenBIOS (a free IEEE1275-1994 Open Firmware implementation) * Open Firmware (a free IEEE1275-1994 Open Firmware implementation) * SmartFirmware (a free IEEE1275-1994 Open Firmware implementation) * GNUFI (a free, UEFI-compatible firmware) * Etherboot (for network booting and booting from raw IDE or FILO) * ADLO (for booting Windows 2000 or OpenBSD) * Plan 9 (a distributed operating system) * memtest86 (for testing your RAM) Supported Hardware ------------------ Coreboot supports a wide range of chipsets, devices, and mainboards. For details please consult: * http://www.coreboot.org/Supported_Motherboards * http://www.coreboot.org/Supported_Chipsets_and_Devices Website and Mailing List ------------------------ Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website: http://www.coreboot.org You can contact us directly on the coreboot mailing list: http://www.coreboot.org/Mailinglist Copyright and License --------------------- The copyright on coreboot is owned by quite a large number of individual developers and companies.
