The guys I got the original program from are working on a dos version of the firmware extractor.  I can promise that they won't want to give out any source code even if they have it.  I guess we just have to wait until they give someone the new version of the extractor so we can get a copy of the firmware.  Anyone who has a gdr-8163b can help find the signals though!

well i think well just have to wait for a dos version, but i think it would be easier to convert it into a xbe file. but they probably dont have teh equiptment to do that do they?

Find: Ready signal, Eject signal, Tray IN and Tray OUT signals
Ready: 5 volts w/o CD, 0 volts w CD
Eject: needs to be between 3.5 and 5 volts
Tray IN: 5v with tray in, 0v w tray out
Tray OUT: 0v with tray in, 5V with tray out.

I took these values from here so they should be correct.

Your english is fine. You only had one mistake, very good for a second language!

Your only mistake was "i find" should have been I found.


Anyone conferm these signals? Is this drive going to require a nand gate, or can we just solder and go like the sd-616t?

I have one of these Hitachi drives and it is slow but it reads the cheapest media. Fry's had some no brand DVD's for $1.75 (50pk) reads them with no problems.

writing a firmware extractor shouldn't be too difficult, I know a little assembley... I'll look into it, it's mostly compatible with 8052's code? www.8052.com/users/disasm/ ...

page 103, the atapi "download microcode" command,
This command enables the host to alter the device’s microcode. The data transferred using the DOWNLOAD
MICROCODE command is vendor specific.
All transfers shall be an integer multiple of the sector size. The size of the data transfer is determined by the
contents of the LBA Low register and the Sector Count register. The LBA Low register shall be used to extend
the Sector Count register to create a 16-bit sector count value. The LBA Low register shall be the most
significant eight bits and the Sector Count register shall be the least significant eight bits. A value of zero in
both the LBA Low register and the Sector Count register shall specify no data is to be transferred. This allows
transfer sizes from 0 bytes to 33,553,920 bytes, in 512 byte increments.
The Features register shall be used to determine the effect of the DOWNLOAD MICROCODE command. The
values for the Features register are:
- 01h – download is for immediate, temporary use.
- 07h – save downloaded code for immediate and future use.
Either or both values may be supported. All other values are reserved.

but if all I need to do, is write a program that sends that command, and then saves the result why do there need to be special versions of the program depending on which chipset the drive runs? ah well, I'll try to figure out how to write an assembley program that runs on a dos boot disk.
