[Bug 1639394] Re: Unable to boot Solaris 8/9 x86 under Fedora 24

[Lev Kujawski]

Hello, I believe I have solved the underlying issue with the attached
patch. Verified against the behavior of an actual i440FX IDE controller.

See https://lists.nongnu.org/archive/html/qemu-
devel/2022-05/msg04229.html .

** Patch added:

Title:
  Unable to boot Solaris 8/9 x86 under Fedora 24

Status in QEMU:
  Expired

Bug description:

  Try several ways without success, I think it was a regression because problem 
seems to be related with ide fixed on 0.6.0:
  - int13 CDROM BIOS fix (aka Solaris x86 install CD fix)
  - int15, ah=86 BIOS fix (aka Solaris x86 hardware probe hang up fix)

  Solaris 10/11 works without a problem, also booting with "scsi" will
  circumvent initial problem, but later found problems related with
  "scsi" cdrom boot and also will not found the "ide" disk device.
