DragonFlyBSD

I believe thats because your motherboard's BIOS is quite broken. Some
suggestions: 1) Update your BIOS 2) Turn of APIC_IO

:I have been unable to get to a login prompt (to boot up) my dragonfly bsd
:installation if I compile a kernel with both SMP and APIC_IO options.
:
:Since it can't boot up, I can only provide pics i took with my phone of what
:happens during boot up, they are at http://www.rumko.net/dragonfly/ and so is
:the kernel config file.

:Hope someone can fix my problem.

Its hard to tell but I think it may be crashing in this bit of code
    in ad_timeout():

/* if retries still permit, reinject this request /
    if (request->retries++ < AD_MAX_RETRIES) {
        ad_requeue(adp->device->channel, request);
    }
    else {
        / retries all used up, return error */
        request->bio->bio_buf->b_error = EIO;    <<<<<<<<<<<<<<<<<<<<< HERE
        request->bio->bio_buf->b_flags |= B_ERROR;
        devstat_end_transaction_buf(&adp->stats, request->bio->bio_buf);
        biodone(request->bio);
        ad_free(request);
    }
    ata_reinit(adp->device->channel);

I'm not sure why, though.  But that isn't the cause of the problem...
    the ATA timeout code may be broken in some way, but a timeout can
    only occur in that manner (theoretically) if interrupt routing isn't
    working, so it is possible that APIC routing is broken in some way.

The fault address is really weird.  It kinda looks to me like the 
    BUF/BIO was free()'d up prior to the ad_timeout() and the memory was
    being used for something else (like to hold text).

What kind of machine is this?  Motherboard and chipset?

How safe would it be to use wine on the winflash utility from DFI?

Safe if you DONT like your computer. I find that a lot of manufacturers
provide either a bootable floppy disk to update your BIOS, or they provide
floppy image of the new BIOS and tell you to use a Windows boot disk, like
Intel does. Is your motherboard manufacturer like that? Worst case scenario,
you'll have to install Windows.

Hi,

About the first point, saying it is not booting with SMP and APIC_IO, I want to
say that, although APIC_IO is somehow broken on many systems, Sephe did a great
work on SMP some months ago. Is it possible for you to try with latest ISO snapshot?

Regarding the second about flashing the BIOS, I think you can use a MSDOS
bootdisk for that. There is a ton of links out there that provide those:

By "not usable at all" you mean by no OS different from Windows?

There are systems which don't have any usable mptable at all, therefore
can't boot anyway with APIC_IO option. As example of such mptable:
