Firmware archive for the N53JM, N53JF and N53JN notebooks, which follows ASUS N53-series naming, though no brand is stated.

Main BIOS archive for the Lenovo IdeaPad S400, 3.74 MB in RAR form. The word main suggests the system BIOS rather than EC firmware, but the name gives no board number or…

BIOS archive for the Dell Vostro 1520, Intel version, compressed to 993 KB. No motherboard number or revision is given, so identify the board from its PCB label before…

Original dump for the Dell Latitude E5440, read from chip U2, a Winbond 25Q32FV 32 Mbit SPI flash.

Compressed RAR package with BIOS firmware for the Samsung NP300E5V laptop, 5.68 MB in size, which suggests more than one image or a large full dump inside.

BIOS ROM for the ASUS K55A notebook, 6.00 MB. This size is unusual for a single SPI chip and may reflect a two-chip layout or a partial region, so check it against the…

Samsung R590 BIOS dump labelled JS01SA, presumably a regional or configuration code, and tagged ok as a working image.

BIOS dump for the Acer Aspire 5515, marked as working. The file has no extension and the name states no version or chip type.

Asus K42Jc BIOS image archive, 1.05 MB, carrying the AS216 tag that likely marks BIOS version 216.

Another copy of a firmware package for the LG W1752ST monitor, sized about 56 KB as a RAR.

BIOS dump for an HP Pavilion dv2000 series notebook, model dv2927la, with tokens suggesting an AMD platform; the rest of the name looks like an uploader tag.

Firmware archive described as working (OK) for a Fujitsu AH531-type laptop, compressed to 3.89 MB in RAR form.

BIOS firmware in FD format for the HP Pavilion dv5-1050ee notebook, 1 MB in size, which corresponds to an 8 Mbit SPI flash chip.

BIOS image for the ASUS K53SV notebook, the name giving only the model with no revision or board details.

RAR archive with BIOS firmware for the ASUS Eee PC 1215N netbook, about 511 KB compressed.

Full datasheet covering the ATmega325, ATmega3250, ATmega645 and ATmega6450 AVR microcontrollers, a 2.69 MB PDF.

Datasheet PDF of 426 KB identified only as doc6318, so the file name gives no clue about the component.

BIOS archive for board DAY0PAMBAF0 at revision F; the DA-prefix numbering is Quanta's motherboard scheme, and the name does not identify the notebook model.

BIOS archive for board 6050A2560201 at revision A03, containing an Outimage.bin, typically the output image produced by a programmer or editing tool ready to be written.

Datasheet for the 2SD1815 in PDF format, 154 KB, catalogued as a schematic. Apart from the type number, the name carries no extra details.

PDF sheet of roughly 41.8 KB for the 5LP02M part, filed under schematics. Only the part number is given; by the series pattern the LP letters likely signify a P-channel…

Datasheet for the 5HP01N part in PDF form, about 27 KB. No device or motherboard is named; the code with an N ending appears to be a package variant of the 5HP01 series.

Combined datasheet PDF of 210 KB covering the 4N25 to 4N28 and 4N35 to 4N37 optocouplers, although indexed as a schematic.

Compact 38 KB PDF datasheet for the 2SD2142K, an NPN transistor named in the Japanese JIS scheme, where the trailing letter marks a specific package or variant.

Only 28.2 KB, this PDF named 2sk123 is catalogued as a schematic, but the name is a JIS transistor number, so a short datasheet is the likely content.

A 134 KB PDF for the 2SK2460N, catalogued as a schematic but almost certainly a datasheet for a discrete transistor, since 2SK numbers under the Japanese JIS system…

The 2SK1473 is the only information the file name gives, and that code follows the Japanese JIS scheme where 2SK means an N-channel FET.

A 117 KB PDF catalogued as a schematic but named after the 2SK1458 part number, so it most likely holds the manufacturer's data sheet for that semiconductor.

PDF for the 2SJ306, about 94.4 KB. The name contains just the transistor type, so no device, board or revision can be stated.

Specification sheet for the 2SD874 transistor in PDF form, about 44 KB, catalogued with the schematics but actually a component datasheet.

Datasheet for the 2SD669 NPN transistor in a small 32 KB PDF, maker not stated in the file name.

PDF document for the 2SC4435, catalogued as a schematic but named after a discrete semiconductor part number rather than a board.

Part number 2SC4324 is the only information in the name of this 468 KB PDF, which is catalogued as a schematic but almost certainly holds the device datasheet.

Reference sheet in PDF format for the 2SC4256, 80.8 KB in size. The file name gives no manufacturer, package or revision details.

A 305 KB PDF for the 2SC4246 transistor. The name states nothing apart from the part number, so the manufacturer and revision have to be read inside the document.

A 274 KB PDF named after the part number 2SC4244, filed under schematics but most likely a component datasheet.
