BIOS image archive for the ASUS K55VM laptop mainboard, revision 2.2 as stated in the name, roughly 3.3 MB in size.

Circuit diagram for the ASUS K73TK laptop, drawn on Compal mainboard LA-7553P at revision 0.2 and provided as a PDF.

At 287 KB this PDF for the 2SK1875 is larger than its neighbours, which may mean extra graphs or pages, though the name says nothing more than the part number.

A 49.7 KB PDF covering the 2SC5576 transistor. Only the part number is present in the name, with no package, manufacturer or revision information.

PDF sheet for the 2SC3935 part, with an _E suffix after the number, filed under schematics at 40.7 KB.

A 195 KB PDF labelled 2SA2060, a part number in the Japanese JIS system where 2SA denotes a PNP bipolar transistor.

PDF datasheet for the 2N5457 N-channel JFET, 111 KB, filed under schematics. The RE suffix in the name is not explained and may mark a reissued or alternate vendor copy…

Catalogued as a schematic, this 67.7 KB PDF is named after the 1SS193 part, followed by an underscore that adds no detail.

Catalogued as a schematic, this 80.2 KB PDF carries the code 249NQ135, which looks like a power diode or rectifier module part number, so a datasheet is the likely…

Full 8.00 MB BIOS read from a GD25Q64 SPI chip, a 64 Mbit GigaDevice part, on an HP 15 laptop tagged USOO; the programmer timestamp dates it to 15 May 2018.

Small 44.2 KB PDF datasheet whose name gives only the part designation SMABZG01, with no manufacturer stated.

BIOS dump for Quanta board DA0P5NMB8E0, revision E, tagged 08A20 and noted as containing DMI data.

Dell Latitude D800 package, RAR format, 1.43 MB, for a Compal LA-1901 board at revision A02. The trailing SEC suffix is unclear and may mark a secondary or partial set.

Schematic for the Lenovo IdeaCentre AIO 510-22ASR all-in-one desktop, covering the Compal LA-D961P mainboard with the CCA20 project code.

BIOS dump for the Apple MacBook Air A1466 with logic board 820-00165-02, marked as the 2015 model, provided as a 4.30 MB RAR.

Boardview for the Microsoft Surface Pro 9 mainboard labelled BB_W MB C4, delivered in a 235 KB zip. It pairs with the matching schematic for the same board marking.

BIOS package for the Lenovo IdeaPad U410 laptop, machine type 4376, built on Quanta motherboard DA0LZ8MB8E0, revision E, and marked as tested.

BIOS dump for the ASUS Eee PC 1201PN, the 12-inch netbook, made for mainboard revision 2.0 according to the name.

Covering the 2SD1817, this 75.8 KB PDF is indexed as a schematic but by name is a component datasheet. No maker or revision is indicated.

PDF document of 41.0 KB for the 2SD2185 transistor, with an _E suffix in the file name that is not decoded here.

For the 2SK2744 this 177 KB PDF provides component-level reference material, although the index lists it among schematics.

Small 89.2 KB PDF labelled 2SJ191, a JIS designation that marks a P-channel FET, so the file is presumably that part's datasheet rather than a board schematic.

Catalogued as a schematic, this 184 KB PDF is named only after the part number 2SC5175, so it is most likely the manufacturer datasheet for that discrete transistor.

Labelled 2SC4835 with an _E suffix, this 41.5 KB PDF is filed as a schematic but refers to a JIS-numbered NPN transistor, indicated by the 2SC prefix.

Catalogued as a schematic, this 190 KB PDF is named after the 2SC2999, a part number in the Japanese JIS scheme where the 2SC prefix marks an NPN bipolar transistor.
