Hi, I am using VORTEX86DX processor, and I can't find a way to write BIOS online through JTAG port. Fortunately, I saw your post. Can you tell me whether to flash through JFLASH.exe? What other devices are needed on the hardware? Can you send me the Jflash.exe file? Thanks!

I'm sorry, but I've since moved on to other projects and don't have the files at hand. You'll have to do some legwork.
This link seems to be up to date.
Re: Vortex86DX - A beastie of it's own (General info and discussion)
Archive jflash127.zip.asc is AES256 encrypted binary. Should be easy to decrypt using "gpg" (or similar) utility with the password provided.
The cable is XILINX Parallel Cable III or any clone. Match output TDI\TDO\TCK etc to jtag port pins on the target device.
I used HP thin client with LPT port and WinXP as a host.
P.S. Make a full backup of your current ROM.
Or at least write down network MAC. It is stored on the same IC. Can be reprogrammed using BIOSMP tool.
Flashing through jtag may reset it to FF's

Thank you very much！, I will try your method.
