the chip was directly connected (desoldered from notebook) with a cable adapter of 3-5cm.. can you tell me an "Intel network card" valid to find?
thanks and congratulations for the work done!

hello, I'm trying to retrieve a notebook with SST25VF040B, but is not recognized by flashrom. I'm using a asus motherboard with Intel P67, Winbond is that mounts originally riconoscituo while the SST25VF040B not. What could I check? thanks

A SST25VF040B should have id1 0xbf, id2 0x258d. The values above look like some sort of corruption. All IDs returned by probe_spi_rdid_generic should have been identical. This corruption can be caused by:
- Wrong voltage for the flash chip. flashrom can't change the default
voltage on Intel chipsets. The SST25VF040B expects 2.7V-3.6V. 2. Wrong speed for the flash chip. flashrom uses 20 MHz on Intel chipsets. 3. Unstable connection to the flash chip. Are the wires too long (longer than 5 cm) or is there a soldering problem?
You could try to use another programmer (e.g. Intel network card) for this flash chip. Maybe that works better.
