In the tasks of maintaining and repairing computers, there is a need for an OS for functional and stress testing. Both during the diagnostic process and after the repair. But often the PCs, laptops arrives for repair with the boot HDD/SSD removed.
Usually, in this case, boot Windows 10 (To Go) from external HDD/SSD. And it's pretty convenient. Since Windows 7 did not have such an opportunity at all. But there are disadvantages - you need to spend time installing and uninstalling device drivers for different generations of hardware, and first boot on each hardware configuration takes too long (Windows logo with "Getting devices ready" screen).
This Linux LiveUSB is designed as an alternative solution to this task. Allows you to check / demonstrate PCs, laptops hardware working, stress-test CPU and GPU, monitor temperature sensors, check S.M.A.R.T. attributes of HDD and NVMe SSD.
Instead of a relatively expensive HDD/SSD with Windows 10 (To Go), even a 2Gb USB flash drive is enough. And several laptops (with hardware of different generations) can be launched from it in copy2ram mode at the same time in turn. Run on each FurMark or Unigine Heaven, and remove the flash drive.
Includes applications such as GPUTest, Unigine Heaven, CPU-X, GSmartControl, GParted, Partimage, Partclone, TestDisk, ddrescue, WHDD, DMDE.
Installation on a FAT32 flash drive with installdog.sh / cmd syslinux.exe. As an alternative, contain config for grub4dos and ventoy_grub.cfg for use with multiboot flash drives.
Features:
- Both UEFI and Legacy/CSM boot modes supported. Including over the network via PXE with NFS. From USB/SATA/NVMe devices, from FAT32/exFAT/Ext2/3/4/NTFS filesystems. Secure Boot is not supported and must be disabled.
- The size of the distribution is optimized for use in copy2ram mode (allows you to remove the USB drive / network cable after loading). In this case, only squashfs modules in use will be copied into RAM.
- Contains three versions of NVIDIA proprietary GPU drivers - current 550.x, and legacy 390.x and 340.x. At boot time, the linuxrc* script automatically determines which driver squashfs module to load (article description in Russian language). Note: AMD and Intel GPUs work with free drivers (don't require installation process, and are already contained as Linux kernel modules + userspace Mesa libraries).
- The default launch option is 64bit Linux 6.10 kernel. NVIDIA 550.x and 390.x driver modules are pre-built.
- Additionally, a 64bit Linux 5.10 kernel is supplied. It must be selected if a legacy 340.x NVIDIA driver is required (390.x is also pre-built). This kernel uses the Broadcom WL WiFi driver for 802.11n adapters, which do not work with free drivers.
- Linux 5.10 kernel built with intel-nvme-remap patch from EndlessOS to make NVMe SSDs available on 8th-10th gen Intel Core i3/i5/i7 platforms with "Intel RST Premium With Optane" option enabled in UEFI Setup.
- For compatibility with older hardware, a live32 i686 version with Linux 6.1 kernel without PAE is included.
- When launch GPUTest (FurMark) or Unigine Heaven on laptop configurations with switchable GPUs (Intel+NVIDIA, Intel+AMD and AMD+NVIDIA) it detected automatically and set necessary environment variables to run on a discrete GPU.
- When booting with Linux 6.1 or 6.10 kernels, the new NTFS3 driver from Paragon is used to mount drives instead of NTFS-3G.
- You can install any software available in Debian and create modules with the necessary additional software. Additional squashfs modules can be activated in run time, not only at boot time.
- Shell scripts and settings can be copied to a flash drive in the live/rootcopy folder and they will be applied at boot time without need to rebuild modules.
- The ability to install using the installdog script to the HDD/SSD of a pre-sale PC / laptop to demonstrate it is functional. The script creates a 2GB FAT32 partition at the beginning of the disk, which is then safe to delete, and does not make changes to UEFI variables (boot options in UEFI firmware).
Build is based on DogLinux - Puppy sized Debian Linux
Bookworm build script. By fredx181
Debian GNU/Linux https://www.debian.org/
Changes from the previous release:
- Updated 2024.10.08 to Debian 12.7 release.
- Build based on
upcoming Debian 12 "Bookworm" release.
- Added MPV player (squashfs modules for both x86-64 and i686).
- Added modules (both x86-64 and i686) with proprietary software for HDD/SSD monitoring Hard Disk Sentinel Linux Edition (FREE). When launch from main menu, it generates a html report that opens in the NetSurf browser. NVMe SSDs are supported.
- Updated Chromium 112, CPU-X 4.5.2, PassMark memtest86 10.4, HDAT2 7.5
- Added memtest86+ 6.10 (with UEFI support), and keep legacy 5.01 version available to run.
