From 42f455054f8301ce18936b583e8354551a4f2c17 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Fri, 8 Jun 2018 13:17:39 -0400 Subject: tests/cdrom-test: Test booting from CD-ROM ISO image file MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We already have the code for a boot file in tests/boot-sector.c, so if the genisoimage program is available, we can easily create a bootable CD ISO image that we can use for testing whether our CD-ROM emulation and the BIOS CD-ROM boot works correctly.
