* Add HOW_TO_DEBUG_WITH_GDB file * Add debug_memtest.sh * Add debug target to Makefile * Add binaries and generated files for debugging to gitignore * Add DEBUG code for memset and memcpy * Add debug additions to Makefile in build32 * Add debug_memtest.sh to build32 [Lionel Debroux: post-merge fixups: removed a couple whitespace changes and a backup file; undone Github squash merge authorship damage.]

# grub-memtest.iso uses GRUB as an intermediate bootloader to allow Memtest86+
|
|
# to be started with the native USB keyboard drivers either enabled or disabled,

# or to be started in a fail-safe mode with SMP and memory identification &
|
|
# speed testing disabled.

#
|
|
# By setting GRUB_CFG to "grub-test", grub-memtest.iso can instead be used for
|
|
# testing the various different boot modes. Upstream GRUB only supports the
|
|
# 16-bit and 32-bit boot protocols, via the "linux16" and "linux" commands.
|
|
# Fedora add support for the EFI handover boot protocols, via the "linuxefi"
|
|
# command, and, since 2019, remove support for the 32-bit protocol, aliasing
|
|
# the "linux" command to either "linux16" or "linuxefi", depending on whether
|
|
# you boot in legacy or EFI mode. Mageia follows Fedora, but restores support
|
|
# for the 32-bit protocol, via the "linux32" command. Other distributions no
|
|
# doubt do their own thing. The boot menu on grub-memtest.iso attempts to
|
|
# support all these options.
