memtest86+ for Debian --------------------- Multiple binary images are provided: - A legacy bios 32bit /boot/memtest86+ia32.bin that uses Linux zImage boot protocol. - A legacy bios 64bit /boot/memtest86+x64.bin that uses Linux zImage boot protocol. - A 32bit EFI Image /boot/memtest86+ia32.efi - A 64bit EFI Image /boot/memtest86+x64.efi These are automatically registered with grub2. For other bootloaders you'll need to do some manual setup (see examples/grub-menu.lst for GRUB Legacy), or to make a boot-floppy, and reboot on this image. 32bit and 64bit ISO Images with EFI and legacy boot support are provided at /usr/lib/memtest86+/ There are some grub2 variable supported in /etc/default/grub: - GRUB_DISABLE_MEMTEST: if true don't add any memtest86+ entries - GRUB_MEMTEST_DISABLE_SERIAL: if true don't add serial entries - GRUB_MEMTEST_SERIAL_PARAMS: custom serial parameters, default is ttyS0,115200 Expected argument is like console=ttySx,y with x being the serial port address (0 = 0x3F8 / 1 = 0x2F8 / 2 = 0x3E8 / 3 = 0x2E8) and y is an optional baud rate to choose from the following list: 9600, 19200, 38400, 54600, 115200 (default if not specified or invalid), 230400. -- Fabio Fantoni Fri, 22 Apr 2022 12:11:26 +0200
