[Bug 277903] Re: Missing Operating System [message at boot]

[TJ]

** Description changed:

  I'm reviving this report since the issue is still present in 14.04 and
  15.10 syslinux, which is used in the various flavour hybrid ISOs, via
  mbr/isohdpfx.{S,bin}
  
  The same system I originally reported in comment #30 is still affected.
  
- The patch that was applied to upstream syslinux MBRs in 2009 as a result
- of this (holding down Ctrl key to force boot device 0x80) is no longer
- present, although the MBR source does contain the definition for reading
- the keyboard state:
- 
- BIOS_kbdflags = 0x417
- 
  Original upstream discussion (March 2009):
  http://www.syslinux.org/archives/2009-March/012254.html
+ 
+ Peter reworked the patches in 2009 and created additional MBRs with the
+ suffix "_c" (press Ctrl to force disk 0x80) and "_f" (unconditionally
+ force disk 0x80).
+ 
+ These images are in the Ubuntu 14.04 package but were removed (in
+ Debian) with:
+ 
+ syslinux (3:6.03~pre19+dfsg-3) unstable; urgency=low
+ 
+   * Also skipping isohd*x_{c,f}.bin in syslinux-common.
