+ information in various README files in drivers/sound, esp. in
+ Readme.cards which you should read first to find out whether your
+ card is supported by Linux.
+ If you have a PnP sound card and you want to configure it at boot
+ time using the ISA PnP tools (read
+ http://www.roestock.demon.co.uk/isapnptools/ (to browse the WWW, you
+ need to have access to a machine on the Internet that has a program
+ like lynx or netscape)), then you need to compile the sound card
+ support as a module ( = code which can be inserted in and removed
+ from the running kernel whenever you want) and load that module
+ after the PnP configuration is finished. To do this, say M here and
+ read Documentation/modules.txt as well as
+ drivers/sound/Readme.modules; the module will be called sound.o.
+ I'm told that even without a sound card, you can make your computer
+ say more than an occasional beep, by programming the PC speaker.

+ * The ESP isn't very bright and will arbitrate

+ * forever if you let it. This value tells
+ * the ESP when it has taken too long to
+ * negotiate and that it should interrupt
+ * the CPU so we can see what happened.

+ * NCR/Symbios chip docs).
+ *

+ * STO = ----------------------------------
+ * (8192) * (Clock Conversion Factor)
+ *
+ * You usually want the time out period to be
+ * around 250ms, I think we'll set it a little
+ * bit higher to account for fully loaded SCSI
+ * bus's and slow devices that don't respond so
+ * quickly to selection attempts. (yeah, I know
+ * this is out of spec. but there is a lot of
+ * buggy pieces of firmware out there so bite me)

+ * This code emulates TT SCSI DMA on the Hades.
+ *
+ * Note the following:
+ *
+ * 1. When there is no byte available to read from the SCSI bus, or
+ * when a byte cannot yet bet written to the SCSI bus, a bus
+ * error occurs when reading or writing the pseudo DMA data
+ * register (hades_psdm_reg). We have to catch this bus error
+ * and try again to read or write the byte. If after several tries
+ * we still get a bus error, the interrupt handler is left. When
+ * the byte can be read or written, the interrupt handler is
+ * called again.
+ *
+ * 2. The SCSI interrupt must be disabled in this interrupt handler.
+ *
+ * 3. If we set the EOP signal, the SCSI controller still expects one
+ * byte to be read or written. Therefore the last byte is transferred
+ * separately, after setting the EOP signal.
+ *
+ * 4. When this function is left, the address pointer (start_addr) is
+ * converted to a physical address. Because it points one byte
+ * further than the last transfered byte, it can point outside the
+ * current page. If virt_to_phys() is called with this address we
+ * might get an access error. Therefore virt_to_phys() is called with
+ * start_addr - 1 if the count has reached zero. The result is
+ * increased with one.

*
- * Alan, could we solve this question once and forever?
- *
- * I believe, datagram sockets should never
- * generate SIGPIPE. Moreover, I DO think that
- * TCP is allowed to generate it only on write()
- * call, but never on send/sendto/sendmsg.
- * (btw, Solaris generates it even on read() :-))
- *
- * The reason is that SIGPIPE is global flag,
- * so that library function using sockets (f.e. syslog()),
- * must save/disable it on entry and restore on exit.
- * As result, signal arriving for another thread will
- * be lost. Generation it on write() is still necessary
- * because a lot of stupid programs never check write()
- * return value.
- *
- * Seems, SIGPIPE is very bad idea, sort of gets().
- * At least, we could have an option disabling
- * this behaviour on per-socket and/or per-message base.
- * BTW it is very easy - MSG_SIGPIPE flag, which
- * always set by read/write and checked here.
- * --ANK
+ * Note: This routine isnt just used for datagrams and
+ * anyway some datagram protocols have a notion of
+ * close down.

-NetBEUI is a rather weird protocol. There are about three different set
-of connection and name spaces here.
-
-Firstly we have an array of 802.2 LLC links acting as reliable inter node
-links for the nodes we are talking to do. We create and tear these down as
-needed. In effect it goes around pretending ethernet is a set of bits of
-wire and running pseudo X.25 over it. The LLC code is elsewhere (net/802).
-
-Secondly we have the netbios name space. When we sit on multiple networks
-we have fun. Netbios isnt routable, so we have to arse around looking on
-all our devices for names.
-
-Thirdly we have logical netbeui sessions on top of the whole heap.
-
- *Don't blame us*
-
-We didn't design the protocol.
