• , , ,

To get rid of the setup utility, you need to follow these instructions below:

Step 1: Boot your Asus computer and wait for it to the Aptio Setup Utility window.

Step 2: Go to Security, expand the Secure Boot Control menu and ensure the secure boot option is disabled.

Step 3: Save and exit the tab, then restart your PC and wait for it to load Aptio Utility settings once again.

Step 4: Navigate to the Boot tab, disable these two options – Secure Boot and Fast Boot.

Step 5: Besides, enable CSM (Compatible Support Module).

Step 6: Save the change and restart the Asus computer. It should boot to the Windows operating system instead of Aptio Setup Utility.

Proprietary device driver

A proprietary device driver is a closed-source device driver published only in binary code. In the context of free and open-source software, a closed-source device driver is referred to as a blob or binary blob. The term usually refers to a closed-source kernel module loaded into the kernel of an open-source operating system, and is sometimes also applied to code running outside the kernel, such as system firmware images…

The 9 Best Secure Routers of 2021

The Linksys WRT3200ACM has Tri-Stream 160 technology that doubles bandwidth to help maintain speed better than most dual-band routers. Additional features such as MU-MIMO technology helps each device stay connected to the network at the fastest possible speed without interfering with the performance of other devices.

Linksys’ Smart Wi-Fi smartphone app also lets you manage and monitor your network from anywhere at any given time, but it’s the open-source aspect that really shines for security-focused router buyers, since you can easily use “packages” from trustworthy open source distributions such as OpenWRT or DD-WRT and establish a secure VPN, monitor and analyze network traffic or detect network intrusions instantaneously. Since the firmware packages are all open source, that also means that they’ve been extensively “peer-reviewed” by security experts, making them much more likely to be free of vulnerabilities that hackers can exploit.

USB-C Introduction: What You Really Need to Know About the Connector Taking Over the World

USB-C capabilities

Whereas USB-A connectors have to be plugged into their ports in a specific orientation, the symmetry of the oval shaped USB-C connector head, along with the pin configuration within it, allows the USB-C connector to be completely reversible…

With two-way charging, a USB-C port has the potential to either output power in order to charge a connected device, or input power from a connected device in order to charge itself.

Alt Mode allows USB-C ports to transfer data/video via multiple interfaces, including the increasingly popular DisplayPort video interface. USB-C ports which are able to transfer DisplayPort signals are either called USB-C DisplayPort or DP Alt Mode. They allow you to connect video sources (e.g. PCs, Blu-Ray players, etc.) and display devices (e.g. TVs, projectors, etc.) that support DisplayPort to each other via their USB-C ports to broadcast high-definition video.

What’s the Difference Between GPT and MBR When Partitioning a Drive?

MBR does have its limitations. For starters, MBR only works with disks up to 2 TB in size. MBR also only supports up to four primary partitions—if you want more, you have to make one of your primary partitions an “extended partition” and create logical partitions inside it. This is a silly little hack and shouldn’t be necessary.

GPT stands for GUID Partition Table. It’s a new standard that’s gradually replacing MBR. It’s associated with UEFI, which replaces the clunky old BIOS with something more modern. GPT, in turn, replaces the clunky old MBR partitioning system with something more modern. It’s called GUID Partition Table because every partition on your drive has a “globally unique identifier,” or GUID—a random string so long that every GPT partition on earth likely has its own unique identifier.

GPT doesn’t suffer from MBR’s limits. GPT-based drives can be much larger, with size limits dependent on the operating system and its file systems. GPT also allows for a nearly unlimited number of partitions.

On an MBR disk, the partitioning and boot data is stored in one place. If this data is overwritten or corrupted, you’re in trouble. In contrast, GPT stores multiple copies of this data across the disk, so it’s much more robust and can recover if the data is corrupted.

GPT also stores cyclic redundancy check (CRC) values to check that its data is intact. If the data is corrupted, GPT can notice the problem and attempt to recover the damaged data from another location on the disk. MBR had no way of knowing if its data was corrupted—you’d only see there was a problem when the boot process failed or your drive’s partitions vanished.

Librem laptop hardware quality? Qubes usability/battery life?

Huh, any idea which ODM?

That’s not something we disclose, and to my knowledge nobody managed to figure out for our existing lineup. Regardless, these aren’t white-box devices we are simply repackaging. We work with an ODM to make customizations to a reference board/design, including (but not limited to) keyboard layout/feel, hardware kill switches, display type, hardware TPM, display type, chassis materials, etc. All of which add significant NRE cost (which we have to pay upfront)

Whole House Audio & Multi-Room Music Systems

• ,

Whole house music and multi-room systems are very popular in homes and living spaces of all shapes and sizes. There are many ways to send music throughout a home, including wired and/or wireless connections that enable control from anywhere. You can use an existing receiver as the center hub, or you can install a completely dedicated whole house music system. The amount of effort involved can range from adding a speaker switch to a receiver, do-it-yourself wired/wireless networking, or something more sophisticated that would require professional installation. However, there are pros and cons to the different methods available.

SSD vs. HDD: What’s the Difference?

• , , ,

An SSD does functionally everything a hard drive does, but data is instead stored on interconnected flash-memory chips that retain the data even when there’s no power present. These flash chips are of a different type than the kind used in USB thumb drives, and are typically faster and more reliable.

The PC hard drive form factor standardized at 5.25 inches in the early 1980s, with the now-familiar 3.5-inch desktop-class and 2.5-inch notebook-class drives coming soon thereafter. The internal cable interface has changed from serial to IDE (now frequently called Parallel ATA, or PATA) to SCSI to Serial ATA (SATA)

An SSD-equipped PC will boot in less than a minute, and often in just seconds. A hard drive requires time to speed up to operating specs, and it will continue to be slower than an SSD during normal use.

Because of their rotary recording surfaces, hard drives work best with larger files that are laid down in contiguous blocks. That way, the drive head can start and end its read in one continuous motion. When hard drives start to fill up, bits of large files end up scattered around the disk platter, causing the drive to suffer from what’s called fragmentation. While read/write algorithms have improved to the point that the effect is minimized, hard drives can still become fragmented to the point of affecting performance. SSDs can’t, however, because the lack of a physical read head means data can be stored anywhere without penalty. Thus, SSDs are inherently faster.

An SSD has no moving parts, so it is more likely to keep your data safe in the event you drop your laptop bag or your system gets shaken while it’s operating.

SSDs make no noise at all; they’re non-mechanical.

An SSD doesn’t have to expend electricity spinning up a platter from a standstill. Consequently, none of the energy consumed by the SSD is wasted as friction or noise, rendering them more efficient.

While it is true that SSDs wear out over time (each cell in a flash-memory bank can be written to and erased a limited number of times), thanks to TRIM command technology that dynamically optimizes these read/write cycles, you’re more likely to discard the system for obsolescence (after six years or so) before you start running into read/write errors with an SSD.
