So far, no Linux driver has been developed. I am quite experienced with driver development, though not for Linux. Background: I work on a DOS-based OS ( http://www.deskwork.de/ ), written in Borland Pascal and Assembler for Protected Mode, thus I'm fairly experienced with driver development from scratch. My plan is to write a driver in BP and release it along with lots of comments and a neat PDF specification into the public domain, ready to be ported to Linux, Zeta or whatever. How far I got: I was able to assign 1 KB of I/O memory to the device (the amount it gets under Windows). At offset 100h, a 512 byte buffer is located. The byte at offset 08h indicates whether a stick is inserted (=01h) or not (=00h). The 512 byte buffer shows strange behaviour (no details here), and I cannot read or write anything yet. Needed: It would be helpful to get in touch with people who develop drivers and/or own a Sony laptop with said drive for testing. I think it's still a quite long way to go. I am currently not subscribed to the kernel mailing list. Kind regards, Konstantin Koll Hansmannstr. 17 44227 Dortmund konstantinkoll@gmx.de
