Firmware archive for the Acer Chromebook 871, built on Quanta board DA0ZARMBAG0, which carries the ZAR project code.

BIOS archive for the K50IE laptop, with AS218 run together in the name, most likely meaning firmware version 218. The zip measures 643 KB.

PDF data for the 2SD2658LS, 31.1 KB, indexed under schematics. The LS ending is part of the type designation and points to a specific variant or package of the 2SD2658…

Part documentation for the 2SC4601 transistor, supplied as a 115 KB PDF and indexed as a schematic.

Brief 28.6 KB PDF titled with the part number 2SC5682, which under JIS rules belongs to an NPN bipolar transistor, so it is presumably a datasheet.

ZIP archive of 18.5 MB named UnlockTool Pro, a software utility rather than a board firmware dump, despite its BIOS category.

MEAnalyzer revision r368 packed as a 7z archive, a tool rather than firmware for a specific board.

Despite the firmware category, the name indicates a setup package for HxD, a free hex editor for Windows, marked as tested and working. It contains no BIOS image itself.

Small 330 KB RAR archive named for BoardViewR4 with a BRD reference, apparently a boardview viewer build or related tool for BRD-format files.

The name carries only the part number 2SD1195, so this 148 KB PDF is best treated as the datasheet for that transistor, even though the index labels it a schematic.

Covering the 2SC4483, this 126 KB PDF is a semiconductor data sheet; the 2SC prefix follows JIS rules for NPN bipolar transistors.

Datasheet PDF for the 2SC4983, 144 KB, recorded in the schematic section of the index. The name holds only the part number.

Windows executable named CHROMEBOOKUNLOCKER, about 9.9 MB, intended by its name as a Chromebook unlocking utility.

Compact 39.6 KB PDF for the 2SD2359, catalogued among schematics but by its name a transistor datasheet.

This 55 KB PDF is labelled 2SK2220 and indexed under schematics, though a part-number name usually means the datasheet of a single semiconductor.

Component sheet for the 2SC3644 in a 120 KB PDF. JIS designation rules assign 2SC to NPN bipolar transistors; no device, board or version is mentioned in the name.

Windows executable named dv7, 4.89 MB, classed as software and most likely a BIOS update or flashing utility for an HP Pavilion dv7, though the name does not confirm its…

Windows executable named BCU, 8.80 MB. On HP systems BCU usually refers to the BIOS Configuration Utility, a command-line tool for reading and changing BIOS settings…
