The four most used tool groups

CPU / PCH swaps, bricked BIOS, broken ME, bad onboard memory, vendor locks: the BIOS problems repair shops meet most.

Intel ME rebuild / quick clean

After a BGA CPU swap, liquid damage or a wrong flash the ME no longer fits: no display, very slow POST, power-off after 30-40 seconds or about 30 minutes. Upload the original dump and rebuild the ME, or quickly clean the ME data.

Universal BIOS unlock, extract and merge

Remove BIOS passwords; extract a programmable BIOS from a vendor .exe update; merge clean vendor data into the original dump (keeping serial numbers); extract EC and other firmware.

Onboard memory tools

Bad onboard memory chips or chips of another size / part: change the memory size and SPD data in the BIOS, disable onboard memory, or turn off channels on AMD.

Dell / HP / Microsoft builds

Vendor-specific locks and layouts: extract and merge Dell BIOS from the vendor package, unlock HP G8-G11 locked BIOS, move the original ME on Microsoft Surface (touch keeps working).

Key feature

The drawing system: schematics, boardviews and silk layouts, online and linked

No viewer software to install. The three kinds of drawing for one board sit together: click a part or net in one, and the other two jump to it.

Schematic

How the circuit is wired: where a signal comes from and goes to

  • Parts / nets list: every part, net, location and pin in the file; search it, click one to step through only the pages where it appears
  • Double-click a reference or net name: copied, and located in the boardview / silk layout
  • Thumbnails for every page; press B to bookmark a page
  • Right-click a word to pin a highlight on every page
  • Pen and sticky notes right on the drawing, saved to your account
  • My notes: note a part or net and mark it bad / OK; repair orders and your own power-on sequences live here too
  • Watermark removal and an eye-care background for long sessions

Boardview

Where each part and test point actually sits on the board

  • Opens the common boardview formats online (.fz, .brd, .tvw, .bdv, .cad, .asc, .bvr, .pcb and others, about twenty)
  • Click a part: selected here and located in the schematic / silk layout
  • Click a pin: the whole net lights up and the schematic searches it
  • Both sides at once, side by side or top / bottom, no flipping back and forth
  • Layer mode for boards with layer data: trace by trace
  • Keyboard: Space flips, R rotates, M mirrors

Silk layout

The reference designators printed on the board, to find parts on the real thing; works with PDFs and photos

PDF and photo silk layouts are no longer a pain: instead of zooming in and hunting by eye, every designator is recognized, so one search or click takes you there.

  • Take a photo of the board with your phone and upload it: within minutes the silkscreen designators are recognized automatically and the photo becomes a clickable, searchable silk layout
  • Multiple pages: several photos or PDF pages of one board (front, back, close-ups) in one window, all covered by the list and search
  • Click a reference mark: selected here and located in the boardview / schematic
  • Type a reference in the search box to search every open file at once
  • My notes written in the schematic or boardview show here too

Shared by all three

Related filesSchematic, boardview, silk layout and BIOS of the same board are grouped automatically and stay linked when opened.
Split viewPut a second file in the same window, side by side or top / bottom, e.g. schematic + boardview.
Notes everywhereA note or a bad / OK mark on a part in the schematic shows in the boardview and silk layout too.
Favorites and recent filesStar a file and open it from My files with one click, on any computer you log in from.
Your own files tooUpload boardviews, schematics or silk layouts from your computer; they open online and link the same way.
Works on phonesPinch to zoom, long-press to locate: read drawings on your phone at the bench.

Intel ME

Intel ME rebuild (single + dual chip)Rebuild the Intel ME after a BGA CPU swap or liquid damage: no display, very slow POST, power-off after 30-40 seconds. Intel ME cleaner (quick)Quickly reset and clean Intel ME data (7th-16th gen, ME 11-20), keeping the original ME version, to fix light ME corruption. ME disableDisable the ME in a BIOS, mainly for CPU test fixtures: test CPUs without reflashing the ME every time.

BIOS unlock, extract, merge

Universal BIOS password unlockRemove BIOS administrator / power-on passwords, and read the password directly from some BIOS; for your own devices or devices brought in by customers. Universal BIOS extractExtract BIOS data from a vendor BIOS update package (.exe and others); HP AMD models give a complete BIOS, and a clean ME can be extracted for merging. Universal BIOS merge (single + dual chip)Merge clean BIOS data from a vendor package (or a good dump of the same board) into the original dump to repair it, keeping the original settings and serial numbers. Universal EC extractExtract EC, KBC, BIOS, PD, USB-C and other firmware from vendor update data or a BIOS file; also converts DDR3 SPD to DDR3L and fixes AMI PFAT decompression errors in ME 15 / 16. BIOS microcode updateUpdate the CPU microcode in a BIOS so the board supports more CPUs; without it a CPU upgrade will not boot.

Vendor specific

Dell BIOS merge and unlockFor Dell laptops and boards: extract BIOS data precisely from the vendor package and merge it with the original dump, or extract only. HP BIOS merge and unlock (G8 - G11)Unlock locked HP G8-G11 BIOS from the original dump and the earliest vendor package, producing the main BIOS and a 32 MB external EC firmware. Microsoft ME buildFor Microsoft Surface: move the ME module from the original BIOS into a working BIOS of the same model, repairing the BIOS without losing touch. Lenovo Wi-Fi card unlockRemove the BIOS error after changing the Wi-Fi card on Lenovo / ThinkPad; also opens hidden menus (advanced, engineering, overclocking, AMD) and removes M.2 and USB restrictions. Colorful / Clevo 32 MB board NVRAM cleanFor Colorful and Clevo-based 32 MB boards: clean the NVRAM to fix hanging at the logo and boot failures.

Onboard memory

Onboard memory utilityBIOS work for onboard memory (DDR4 / DDR5 and others): change the memory size, inject SPD data, disable onboard memory, extract SPD, with checks. Onboard memory channel disable (AMD)Change the memory channel switches in AMD DDR4 BIOS: turn off or keep some or all channels, with empty-slot protection.

Locked CPU / PCH board swap

Locked CPU / PCH board swap (Intel) (single + dual chip)Intel CPUs / PCHs locked to their board do not boot on another board: move the boot key from the original BIOS too, with the ME merged automatically. Locked board with an unlocked CPU / PCH (Intel)Release the binding between a locked board’s BIOS and its original locked CPU / PCH, so a standard (unlocked) CPU or PCH is not locked to it. Locked board key transfer (Intel CPU or PCH)Move the boot key of a locked CPU / PCH between single-chip BIOS boards (use “Locked CPU / PCH board swap” for dual-chip boards).

Serial number / DMI

Universal serial number editWith the old serial number known, change the serial number in the original BIOS directly. Universal serial number copyCopy the serial number from the original dump into a vendor BIOS that has none. Universal DMI copyCopy the serial number and other DMI data from the original dump into a factory BIOS or another dump of the same model. Lenovo DMI copyFor Lenovo BIOS only: copy the DMI data from a source file into a target file. Apple serial number editChange and repair the serial number in MacBook BIOS, for all Intel-based Apple models (with T2 and earlier). Apple serial number copyCopy the serial number from the original dump into a factory Apple BIOS that has none.

Dual-chip BIOS

Dual-chip BIOS joinJoin the data of two BIOS chips into one complete BIOS before ME changes or merging. Dual-chip BIOS splitSplit one complete BIOS into two parts for the two chips of a dual-chip board.

Boardview

Universal boardview converterConvert or repair many boardview formats into .fz that boardview software and our online viewer open perfectly (incl. huge Allegro files, ASUS web boardviews, Teboview password removal).
