 # Hardware FAQ
  
-## What is this FAQ for?
-
-This FAQ addresses hardware-specific issues relating to the NodeMcu firmware on
-NoceMCU Inc Devkits and other ESP-8266 modules.
-
-## Hardware Specifics
-
-## Why file writes fail all the time on DEVKIT V1.0?
-
-NodeMCU DEVKIT V1.0 uses ESP12-E-DIO(ESP-12-D) module. This module runs the
-Flash memory in [Dual IO SPI](#whats-the-different-between-dio-and-qio-mode)
-(DIO) mode. This firmware will not be correctly loaded if you use old flashtool
-versions, and the filesystem will not work if you used a pre 0.9.6 firmware
-version (<0.9.5) or old. The easiest way to resolve this problem s update all
-the firmware and flash tool to current version.
-
--   Use the latest [esptool.py](https://github.com/themadinventor/esptool) with
-DIO support and command option to flash firmware, or 
-
--   Use the latest [NodeMCU flasher](https://github.com/NodeMCU/NodeMCU-flasher) 
-with default option. (You must select the `restore to default` option in advanced
-menu tab), or 
-
--   Use the latest Espressif's flash tool -- see [this Espressif forum
-topic](http://bbs.espressif.com/viewtopic.php?f=5&t=433) (without auto download
-support). Use DIO mode and 32M flash size option, and flash latest firmware to
-0x00000. Before flashing firmware, remember to hold FLASH button, and press RST
-button once. Note that the new NodeMCU our firmware download tool, when
-released, will be capable of flashing firmware automatically without any button
-presses.
-
-## What's the different between DIO and QIO mode?
-Whether DIO or QIO modes are available depends on the physical connection
-between the ESP8266 CPU and its onboard flash chip. QIO connects to the flash
-using 5 data pins as compared to DIO's 3. This frees up an extra 2 IO pins for
-GPIO use, but this also halves the read/write data-rate to Flash compared to 
-QIO modules.
