The identifier YA-4A1 94V-0 refers to a specific motherboard marking, commonly found in various budget and consumer-grade laptops. It is often associated with the ASUS X200MA series and certain DEXP or Toshiba Satellite notebook models. BIOS Bin File Report Associated Hardware: ASUS X200MA (specifically model KX265D). DEXP notebooks (e.g., P/N: 6-77-W970TUQ0-D03-2P#10). Toshiba Satellite L850 (TMT YA-4A1 variant). File Specifications:
File Size: Typically 2.97 MB (or 3MB nominal) for the ASUS X200MA variant.
Markings on Board: Users frequently find "YA-4A1 94V-0 E114139" printed on the PCB.
Purpose: This binary (.bin) file is a "dump" of the motherboard's firmware. It is used for low-level BIOS recovery or flashing using an external programmer (like a CH341A) when the laptop is "bricked" and cannot boot into the standard ASUS EZ Flash utility. Technical Warnings ya-4a194v-0 bios bin
Platform Identification: The "94V-0" mark is a standard UL flammability rating for the circuit board material, not a unique motherboard model number. Always verify the specific laptop model (e.g., X200MA) before flashing to avoid permanent hardware damage.
Firmware Dumps: Reliable dumps can often be found on community-driven repositories like the BIOS ARCHIVE Telegram or specialized repair forums like Geekdais.

Reviving the ASUS X200MA: A Guide to the YA-4A1 94V-0 BIOS BIN
If you are a laptop repair technician or a DIY enthusiast, you’ve likely encountered an ASUS X200MA
that refuses to boot. Often, the culprit isn't a hardware failure but a corrupted BIOS chip. Specifically, for motherboards marked with the revision YA-4A1 94V-0, having the correct BIOS BIN file is the difference between a working laptop and a paperweight. 🛠 Hardware Profile
Before flashing, ensure your motherboard matches these specifications to avoid a "brick" scenario: Motherboard Model: ASUS X200MA Revision Code: YA-4A1 94V-0 E114139 Common CPU: Intel Celeron (e.g., N2830 or N2840) BIOS Chip Type: typically 8MB (64Mbit) SPI Flash IC 📥 When do you need this BIN file?
A standard BIOS update via the Windows "Easy Flash" tool won't work if your laptop can't turn on. You need the raw .BIN or .ROM file and an external programmer (like the CH341A) if you experience: The string "ya-4a194v-0 bios bin" appears to refer
No Power/No Display: The lights turn on, but the screen stays black.
Boot Loops: The laptop restarts repeatedly before reaching the ASUS logo.
BIOS Password Lock: If the supervisor password is forgotten and cannot be reset via CMOS. ⚡ How to Flash the BIOS
Backup First: Always read and save your original (corrupted) BIOS chip content before overwriting it.
Verify the Revision: Ensure the board says YA-4A1 94V-0. Using a BIOS from a different revision (like the X200MA rev 2.0) can cause keyboard or touchpad malfunctions.
Use an External Programmer: Connect your SPI programmer to the chip (using a clip or by desoldering).
Write the New BIN: Load the ASUS X200MA YA-4A1 BIOS into your software and hit "Write". ⚠️ Important Note on "Clean ME"
If your laptop turns on but takes 30 seconds to show the logo, or if the fan runs at full speed constantly, the replacement BIOS may need a Clean ME (Management Engine) region. Many technician-uploaded BIN files already have this cleared, but keep it in mind if you experience performance lag.

Align pin 1 of the clip (marked with a dot or triangle) with pin 1 of the chip (usually near a beveled corner). Connect wires:
| CH341A Pin | SOIC8 Chip Pin | Function | |------------|----------------|-----------| | 1 (CS) | 1 (CS) | Chip select | | 2 (MOSI) | 2 (DO) | Data out | | 3 (MISO) | 5 (DI) | Data in | | 4 (CLK) | 6 (CLK) | Clock | | 5 (GND) | 4 (GND) | Ground | | 8 (VCC) | 8 (VCC) | Power (3.3V) |
Do not connect VCC until all other wires are secure.
| Tool | Recommended Model | Approx. Cost | |------|------------------|---------------| | SPI Flash Programmer | CH341A (Black or Green PCB) | $5–$15 | | SOIC8 test clip | Pomona 5250 (or generic) | $4–$20 | | Dupont jumper wires (female-to-female) | 10-20 cm length | $2–$5 | | Optional: 1.8V adapter | For low-voltage flash chips | $5–$10 |
