4Subject: [PATCH] add new option -eltorito-platform
5
6Mkisofs now correctly supports El Torito multi boot entries by introducing
7a Boot Dection Header before a list of alternate boot entries.
8
9New option -eltorito-platform allows to set the El Torito platform id
10for a boot entry or for a list of boot entries. Supported values for
11the parameter are:
12- x86 the standard value vor x86 based PCs
13- PPC the Power PC platform
14- Mac The Apple Mac platform
15- efi EFI based boot for PCs
16- # an arbitrary numerical value
17
18Upstream-Status: Inappropriate [port from cdrtools]
