3.1 | 45 | == Installation and configuration : hands-on Notes == |
| |
2.1 | 46 | |
| |
3.1 | 47 | === Accessing the components === |
| |
2.1 | 48 | |
| |
3.1 | 49 | A single latch on the bottom of the PC unlocks the service cover, which then slides off to provide access to the main internal components. |
| |
2.1 | 50 | |
| |
3.1 | 51 | Replacing the battery, RAM modules, storage drives or the CMOS battery presents no particular difficulty. |
| |
2.1 | 52 | |
| |
3.1 | 53 | === Boot and USB devices === |
| |
2.1 | 54 | |
| |
3.1 | 55 | ==== Boot modes ==== |
| |
2.1 | 56 | |
| |
3.1 | 57 | The UEFI offers three boot modes: Legacy, UEFI with CSM, and UEFI without CSM. |
| |
2.1 | 58 | |
| |
3.1 | 59 | Results show that "UEFI with CSM" mode works best for booting from a USB device. |
| |
2.1 | 60 | |
| |
3.1 | 61 | ==== Boot priority ==== |
| |
2.1 | 62 | |
| |
3.1 | 63 | Boot priority is configured in the "Advanced / Boot" section of the BIOS: navigate to the desired entry, use the "+" key to promote it to the top of the list, then press "Enter" to save. |
| |
2.1 | 64 | |
| |
3.1 | 65 | Bootable USB devices (USB drives, external disks) work in both USB 2.0 and USB 3.0. |
| |
2.1 | 66 | |
| 67 | ==== Observations ==== | ||
| 68 | |||
| |
3.1 | 69 | * Booting via USB 2.0 is slower, though the Live Linux environment remains responsive once loaded |
| 70 | * With Ventoy, booting works in both Grub and Grub2 mode | ||
| 71 | * GPT partition tables were confirmed to work as expected | ||
| 72 | * A Zalman enclosure in CD-ROM emulation mode, with a hard drive using an MS-DOS partition table, produced a boot error (Unable to find a medium containing a live file system) | ||
| |
2.1 | 73 | |
| |
3.1 | 74 | (The root cause has not been definitively identified. An MS-DOS partition table might be incompatible with this UEFI implementation, though the CD-ROM emulation remains a possible contributing factor.) |
