Recently, I purchased a cheap Intel Atom-based Windows 8 tablet (the DigiLand DL801W) that was being sold at a very low price ($15 USD, although the shipping to Canada negated much of the savings) because it would not boot into Windows – rather, it would only boot into the UEFI shell and cannot be interacted with without an external USB keyboard/mouse.
The patient, er, tablet
The tablet in question is a DigiLand DL801W (identified as a Lightcomm DL801W in the UEFI/BIOS data). It uses an Intel Atom Z3735F – a 1.33GHz quad-core tablet SoC (system-on-chip), 16GB of eMMC storage and a paltry 1GB of DDR3L-1333 SDRAM. It sports a 4500 mAh single-cell Li-ion battery, an 8″ 800×1200 display, 802.11b/g/n Wi-Fi using an SDIO chipset, two cameras, one microphone, mono speaker, stereo headphone jack and a single micro-USB port with USB On-The-Go support (this allows the port to act as a USB host port, allowing connections with standard USB devices like keyboards, mice, and USB drives).
