SB600 on HP6715b laptop finds no bootable devices.

[euan]

HP 6715b laptop (very nice too) SB600 IDE device, single channel (Vendor 0x1002 Device 0x4380) SB600 SATA Device (Vendor 0x1002, Device 0x438c)

I don't have serial debug (yet) so screen shots attached.

Ahci driver debug

oh yeah I added some code to force the controller into AHCI mode, but I think it was happily already in AHCI mode anyway on my bios (there's no options to force another mode)

Some log output from linux (yeah not much of use)

I found what the issue is from a post over at openbsd.

My laptop has overlapping memory regions:

SB600 AHCI Bar[5]  @ D0609000-D0609100 (size 100h)
SB600 Audio Bar[0] @ D0608000-D060C000 (size 4000h)

I confirmed this is the issue by adding a function in pci_fixup.c currently it just disables the audio device, and sets the bar to 0. I plan to change this to search for these two devices, check that the addresses match, and if they do (make the assumption that this pc is a an HP6715b) and move one of the BARs to an unallocated region.

I implemented a version using GetNthPciInfo() but it doesn't seem to work at all. Perhaps this api isn't quite ready yet at this stage in boot. so i'll try again tomorrow using some static variables in pci_fixup. slightly more hackish but should do the trick.

patch attached to disable the audio device for now. will need to look into remapping in a future version. AHCI now works!

[luroh]

euan, is this still a problem with a recent version of Haiku?

[scottmc]

Can you recheck this with a recent Haiku build?

[luroh]

euan, if you and the laptop are still around, could you please check with R1 Alpha 4.1?
