[Qemu-devel] [Bug 1191326] Re: QNX 4 doesn't boot on qemu >= 1.3

[Lukas Jirkovsky]

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. Run qemu such as "qemu-system-i386 -bios /path/to/seabios/bios.bin -hda 
qnxdisk ..."

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.  I 
updated my qemu from version
  to newer and QNX4 doesn't start any more. All is ok on version 1.2 but when I 
try to use any newer version
  (1.3, 1.4, 1.5)  QNX4 doesn't boot.  I tried on windows and linux ubuntu 
hosts - effects are the same.

  When virtual machine boots qnx bootloader loads and starts operating system. 
In the next step
  qnx starts its ide driver, which detects qemu harddisk and cdrom. Problem 
starts when operating system
  tries mount partition - an error occur and qnx stop booting procedure:

  mount -p "No bios signature in partition sector on /dev/hd0"

  I have tried install qnx from cdrom but it seems that there is the same 
problem. QNX installer boot from
  cdrom, detects hard disk and cdrom, but cdrom can't be mounted in the next 
step of installation procedure.
