when you look "Error Writing Fail. Status Code 4.", press start, press A, create screenshot from console

need buy MX29L3211 and create dual bios

VA1 board and latest Dreamshell from Github.
I have already replaced the bios chip with MX29LV160 and flashed it with the Dreamshell bootloader. The Dreamshell folder is on a CF card.

Connected a MX29L3211 with the corresponding legs of MX29LV160.
Pin12 of MX29L3211 and MX29LV160 is connected with 3.3V via 10k resistor and you can switch between the two chips by connecting pin12 with diode D501.
Pin1 of MX29LV160 is connected with 3.3V
Pin44 of MX29LV160 is connected with Pin9 of IC502.
Pin1 of MX29L3211 is connected with Pin9 of IC502.
Pin44 of MX29L3211 is connected with 3.3V via 10k resistor respectivley ground : depends on which half of the chip you want to flash.
