vaio : openbsd can't find storage on installation

[hd77]

hello

i tried to installed openbsd on a vaio laptop
here are the specs :

model : PCG-3112M
product name : VPCZ13A7E


problem is, openbsd installer doesnt detects any storage at all, even if a ssd is well present.
there is NO bios option to switch from raid/ahci/ide.
insyde bios could only handle less ten option except time/boot features :
TPM + intelHT.

thank you for helping!

Please post an OpenBSD dmesg.

the openbsd dmesg (from installation) is already at the end of the pastebin

Thank you for pointing me to your dmesg. I had not read through the first 2000 lines of your pastebin to discover it.

I can see the hardware RAID controller:

pciide0 at pci0 dev 31 function 2 "Intel 82801HBM RAID" rev 0x05: DMA, channel 0 wired to native-PCI, channel 1 wir   2019 ed to native-PCI
pciide0: using apic 2 int 22 for native-PCI interrupt

This lead me to the following thread on the tech@ mailing list: https://marc.info/?t=133845473300002&r=1&w=2

You could apply the patch discussed in that thread. Alternatively, you might be able to find a BIOS update that would permit you to disable the hardware RAID controller.

Please note: OpenBSD 7.1 support ended on April 10, 2023. Only the most recent two releases are supported. OpenBSD 7.4 is the most recent release, with 7.5 expected in a matter of days.

hello

thank you for your reply
well, there is no bios update on that laptop
however, is it possible to apply the patch from the openbsd installer process itself? i mean, without the whole compilation process?
as i guess it cannot be compiled on a non openbsd machine?
i dont have another one here now..

thank you

The thread jggimi references is a needed change to the source code. You will need to manually integrate these changes into the current source base, and recompile the kernel yourself. The release(8) manpage describes everything you need to do in order to experiment with this proposed fix.

.. as i guess it cannot be compiled on a non openbsd machine?

Correct. You can use your existing system assuming you have the source downloaded and sufficient disk space.

Some additional notes:

• The recommended patch is 12 years old, and will need to be reworked to fit into a modern OpenBSD. In 2013, the AHCI driver modules were split into PCI and non-PCI hardware attachments, and the module where this patch would need to be applied has changed. It is now /usr/src/sys/dev/pci/ahci_pci.c.
• Without a separate kernel building platform, hd77 would require non-RAID storage, such as USB-attached storage, in order to use this Sony laptop with OpenBSD.
• In order to have this patch apply to the RAMDISK kernel, a complete release(8) would be needed, so that the revised kernel could be made available on install media.
