The wiki is being retired!

Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to Contributions welcome!

This page describes how to use coreboot on the ASUS A8V-E Deluxe mainboard. It is maintained by Uwe Hermann.

Building coreboot

Currently there is no special target for the ASUS A8V-E Deluxe in coreboot. Instead, we use the ASUS A8V-E SE target.

You have to apply the following patch to svn so the board boots (at least when using a Sempron CPU which doesn't seem to support an LDT frequency of 1000MHz):

Index: src/mainboard/asus/a8v-e_se/cache_as_ram_auto.c
--- src/mainboard/asus/a8v-e_se/cache_as_ram_auto.c     (revision 3127)
+++ src/mainboard/asus/a8v-e_se/cache_as_ram_auto.c     (working copy)
@@ -308,7 +308,7 @@
        needs_reset |= optimize_link_incoherent_ht(sysinfo);

        /* Fixme it assumes that 1000MHz LDT is selected. */
-       needs_reset |= k8t890_early_setup_car(16, 0x6);
+       needs_reset |= k8t890_early_setup_car(16, 0x5);

        if (needs_reset) {
                print_debug("ht reset -\r\n");

Then, place your payload (usually FILO) into /tmp/filo.elf and build coreboot as usual:

$ cd target
$ ./buildtarget asus/a8v-e_se && cd asus/a8v-e_se/asus_a8v-e_se && make

The resulting coreboot.rom (512 KB) can now be flashed on a ROM chip.

So far it boots up to a FILO prompt for me, but there is an issue with IDE drive detection, it seems. I'll fix this, and also test SATA drives, those might already work fine.
