Pegatron Sdis1 -

When a NIC fails, the MAC address leads you to the hardware vendor. If ipconfig /all (Windows) or ifconfig (Linux) shows a physical address belonging to Pegatron SDIS1, you should download network drivers from Pegatron’s support site or the motherboard manufacturer—not from the brand of the PC case.

The SDIS1 is built on Intel’s "Braswell" architecture, which was designed for entry-level desktops and laptops around 2015–2016. When a NIC fails, the MAC address leads

This motherboard is older (circa 2012-2013), so modern upgrades are limited, but it still makes a decent budget office PC or home server. Video Output: HDMI and DisplayPort, supporting dual monitor

The "SDIS1" designation is cryptic, but its physical manifestations are not. You will typically encounter hardware containing a Pegatron SDIS1 MAC address in three primary environments:

Yes, you read that correctly. While Apple designs its own custom silicon (M1, M2, etc.), the auxiliary components—including the Ethernet controller on older iMacs and the Wi-Fi/Bluetooth module on certain MacBooks—have been sourced from Pegatron. Network scans of Apple devices occasionally reveal a "Pegatron SDIS1" MAC address for the secondary interface (e.g., the Thunderbolt Ethernet dongle or the Bluetooth radio).

Automatic network discovery tools (like nmap, Lansweeper, or SolarWinds) use OUI lookups to guess the device manufacturer. If your inventory system shows "Pegatron SDIS1" on every desktop, that is fine. But if you see that same OUI on a server rack or a printer VLAN, you have found a rogue device. Because SDIS1 is most commonly used for client motherboards, its presence in a data center is a red flag.
