Now that I know what it is, I'm not so sure that I want to know :-) I think it's a very good idea, but a lot of the LSM entries are now out of date. The reason I discovered this is that I now have a Hypertext link to the LSM from my Linux WWW server. I simply made ftp links to the Site?: entries from the LSM database entries. I went through and was randomly trying entries, and much to my dismay the first 10 I tried didn't work due to the Site: references being out of date. I did enevtually find some that worked, but the majority that I tried did not work. I guess what I'm actually trying to say is, if you have an lsm entry, please check it and make sure that it is up to date. You're bloody insane if you think I'm going to go through and check over 1100 entries to check for their correctness :-) &y -- Andy Burnett -- burnett@baldrick.cecer.army.mil US Army Corps of Engineers -- Construction Engineering Research Lab ------------------------------ From: fnord@cs.mcgill.ca (Andrew KUCHLING) Subject: Missing socket features? linger and SOMAXCONN Date: Fri, 29 Oct 1993 16:44:41 GMT I originally posted this message to comp.os.linux.help, and got no response, so I'm desperately reposting to c.o.l.misc. I'm trying to port a library to Linux, so I can run a corporate scheduling program; the library uses sockets a great deal, and was originally written to run under HP-UX and AIX. At one point in the code, there is a definition requiring a structure called linger, defined as: struct linger {int l_onoff, l_linger}. This is in sys/socket.h on the other operating systems; as far as I can tell, this doesn't exist in Linux. Is this now in the new version of gcc's libraries, or does it simply not exist under Linux? Second question: the code also refers to a #define'd label, SOMAXCONN. Again, this isn't mentioned anywhere in the include files. However, the Linux Doc. Project's man page for listen(2) has the following note: BUGS The backlog is currently limited (silently) to 5. [Docu- menter's note: is this true for Linux?] I repeat the documenter's question: is this value of 5 correct? Thanks for your help.

Its a nice card. Its running Tseng's ET-4000/w32 Accelerator chip. It gives me about 2.2X the performance of an old Trident 8900C 1MB using 3dbench under DOS (Trident = 18 FPS, Hercules = 44 FPS - DX2-66 CPU).

Its total hardware compatible with the ET-4000 and I've had no problems running X under linux. Its definitely faster than my Trident but I don't have the Xstones program to tell you how much.
