BIOS image for a Dell Wyse thin client with model code D90B7, read from a Macronix MX25L1605 flash chip in SOIC16 package. The 1.18 MB RAR suits recovery of a unit that fails to boot or shows no output after corrupted firmware. An MX25L1605 holds 16 Mbit, so the image should be 2 MB once extracted. Since the SOIC16 package differs from common 8-pin clips, use a correct adapter or socket on your programmer, and save the existing contents before writing.
