It turns out modifying code is not needed at all. The only thing that is needed is to configure SeaBIOS with CONFIG_ATA_DMA=y. So the steps needed to make QNX 4 work on current QEMU are 1. Download SeaBIOS source and make sure the configuration has CONFIG_ATA_DMA=y set 2. Build SeaBIOS 3.

[Qemu-devel] [Bug 1191326] Re: QNX 4 doesn't boot on qemu >= 1.3
Hi, I had the same problem, and maybe it can help. I wrote my own toy OS with a PATA / IDE driver back in 2012 using older version of QEMU and everything worked fine. These days, I tried that on a recent version (2.5) and it failed with exactly the same behaviour - lots of zeros being written during a DMA transfer. After some research, I found that the behaviour that was changed with 1.3 is that the bus master configuration bit (bit 2 of the PCI command register) is now emulated, and my driver did not set this bit. Apparently, the BIOS does not set it either, so it was off and the DMA transfer silently failed and only wrote zeros. So I added some code to my init routine that sets this bit, and voila - it worked. I have tried 1.2, 1.3 and 2.5.0 and this works with all of them. I do not know the internals of QNX, but I learned that apparently also Linux did not set this bit in older version, so it might very well be that QNX does not set it either and this is the issue. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1191326 Title: QNX 4 doesn't boot on qemu >= 1.3 Status in QEMU: Confirmed Bug description: I am using virtual machine with QNX4 operating system installed on it.

[Qemu-devel] [Bug 1191326] Re: QNX 4 doesn't boot on qemu >= 1.3
I wonder - would be a record using rr of any help? I can create record
for QEMU 1.2.0 where it works and on current QEMU.
Also, I did a bit of debugging myself around the DMA code as per comment
#3 it was introduced in a commit that changed some of the DMA. What I
did was that I added some debug printfs [1] to dma_memory_rw() to QEMU
1.2.0 and to QEMU 2.11.1.
I noticed on thing - there is a big difference between writes between the two
versions.
Because this stuff is completely outside my knowledge, I don't know whether
this is important or not, but better more information that not enough. For
recent versions of QEMU I see a few 16 B writes from address 0x6d10 and
addresses close to it which contain some data. Immediately after that there is
a ton of 8B writes from addresses starting at 0x102004 which contain zeros
only. On the other hand, the QEMU 1.2.0 is missing the initial 16B writes, but
then there's even more 8B writes from addresses around 0x102004 which contain
some data instead of zeros like in the current version.
[1] the printf looks like this:
printf("DEBUG: DMA %s at address %lx %lu bytes: ", ((dir ==
DMA_DIRECTION_FROM_DEVICE) ? "read" : "write"), addr, len);

[Qemu-devel] [Bug 1191326] Re: QNX 4 doesn't boot on qemu >= 1.3
This is still a problem with QEMU 2.11. Note that the problem in #10 is unrelated to the issue (though GUI works for with the the demo floppy). The problem mentioned in this bug is related to a QNX that is already installed to a disk. Unfortunately the QNX demo floppy that was once free and which can be still found on the internet does not allow installation to disk, so it can't be used to reproduce the bug. At work we still maintain an application for QNX 4.25 so I can help debugging it, but I don't know where to start. Currently we use VirtualBox and VMware, but I personally would prefer QEMU much more.

Eventually all dma functionality will be folded into AddressSpace, but we have to start from something.
