Non-functional since U2/Uturn code is not ready yet (I'm working on it) and not documented (let's not go there again right now). And even if it were ready, I need to hack in some sort of an "I/O tree" in order to support more than one U2/Uturn. K-class can have multiple U2/Uturns. The core I/O board has a NCR 53c720 chip with zalon - Richard Hirst is working on that already. AFIAK, Zalon isn't documented but it's trivial to initialize and the real problem is support for c720 chip in linux. AFAICT, Built-in LAN, PS/2, serial ports, and SE SCSI are off a LASI. Same chip as what's documented for the A180/712/et al. But the firmware might be reporting them differently...someone who cares will have to figure this out. I doubt documents or code for the gecko-boa (GSC to HP-PB bus converter) will ever get published....and even if it did, getting docs for the HP-PB (aka NIO) devices is another huge hurdle. Look for a "HARRIER" (card carrier for K-class, provides 4 "gsc" "slots") if you don't already have one. At least some of the GSC devices (like tachyon, c720) will get or are supported already. > What is the status of the J210XC and will I be able to create > a functional Linux environment for it(the J210) if I wanted to > start coding? (currently running 10.20) Once the U2/Uturn support is in place and user space stabilizes, yes. Audio and graphics continue to be a problem WRT documentation and code. I don't know what's up with "WAX" (EISA) support. Matt, I didn't see a J210XC in the HW database. (http://www.thepuffingroup.com/parisc/hw.html) Since you asked about status and I've written this detailed reply, I'd consider you a real dork at this point if you didn't enter the J210XC into the HW database. Could you please? (thanks in advance :^) grant Grant Grundler Unix Development Lab +1.408.447.7253
