+ Theory of Operation
+
+I. Board Compatibility
+
+This device driver is designed for the 3Com 3c515 ISA Fast EtherLink XL,
+3Com's ISA bus adapter for Fast Ethernet. Due to the unique I/O port layout,
+it's not practical to integrate this driver with the other EtherLink drivers.
+
+II. Board-specific settings
+
+The Corkscrew has an EEPROM for configuration, but no special settings are
+needed for Linux.
+
+III. Driver operation
+
+The 3c515 series use an interface that's very similar to the 3c900 "Boomerang"
+PCI cards, with the bus master interface extensively modified to work with
+the ISA bus.
+
+The card is capable of full-bus-master transfers with separate
+lists of transmit and receive descriptors, similar to the AMD LANCE/PCnet,
+DEC Tulip and Intel Speedo3.
+
+This driver uses a "RX_COPYBREAK" scheme rather than a fixed intermediate
+receive buffer. This scheme allocates full-sized skbuffs as receive
+buffers. The value RX_COPYBREAK is used as the copying breakpoint: it is
+chosen to trade-off the memory wasted by passing the full-sized skbuff to
+the queue layer for all frames vs. the copying cost of copying a frame to a
+correctly-sized skbuff.
+
+
+IIIC. Synchronization
+The driver runs as two independent, single-threaded flows of control. One
+is the send-packet routine, which enforces single-threaded use by the
+dev->tbusy flag. The other thread is the interrupt handler, which is single
+threaded by the hardware and other software.
+
+IV. Notes
+
+Thanks to Terry Murphy of 3Com for providing documentation and a development
+board.
+
+The names "Vortex", "Boomerang" and "Corkscrew" are the internal 3Com
+project names. I use these names to eliminate confusion -- 3Com product
+numbers and names are very similar and often confused.
+
+The new chips support both ethernet (1.5K) and FDDI (4.5K) frame sizes!
+This driver only supports ethernet frames because of the recent MTU limit
+of 1.5K, but the changes to support 4.5K are minimal.

- This driver is for a 16K adapter. It should work fine on the 64K
- adapters, but it will only use one of the 4 banks of RAM. Modifying
- this for the 64K version would require a lot of heinous bank
- switching, which I'm sure not interested in doing. If you try to
- implement a bank switching version, you'll basically have to remember
- what bank is enabled and do a switch everytime you access a memory
- location that's not current. You'll also have to remap pointers on
- the driver side, because it only knows about 16K of the memory.

+ *
+ * FutureDomain MCS-600/700 v0.2 03/11/1998 by ZP Gu (zpg@castle.net)
+ *
+ * This driver is cloned from fdomain.* to specifically support
+ * the Future Domain MCS 600/700 MCA SCSI adapters. Some PS/2s
+ * also equipped with IBM Fast SCSI Adapter/A which is an OEM
+ * of MCS 700.
+ *
+ * This driver also supports Reply SB16/SCSI card (the SCSI part).
+ *
+ * What makes this driver different is that this driver is MCA only
+ * and it supports multiple adapters in the same system, IRQ
+ * sharing, some driver statistics, and maps highest SCSI id to sda.
+ * All cards are auto-detected.
+ *
+ * Assumptions: TMC-1800/18C50/18C30, BIOS >= 3.4
+ *
+ * LILO command-line options:
+ * fd_mcs=<FIFO_COUNT>[,<FIFO_SIZE>]

+
+ NOTES ON USER DEFINABLE OPTIONS:
+
+ DEBUG: This turns on the printing of various debug information.
+
+ ENABLE_PARITY: This turns on SCSI parity checking. With the current
+ driver, all attached devices must support SCSI parity. If none of your
+ devices support parity, then you can probably get the driver to work by
+ turning this option off. I have no way of testing this, however, and it
+ would appear that no one ever uses this option.
+
+ FIFO_COUNT: The host adapter has an 8K cache (host adapters based on the
+ 18C30 chip have a 2k cache). When this many 512 byte blocks are filled by
+ the SCSI device, an interrupt will be raised. Therefore, this could be as
+ low as 0, or as high as 16. Note, however, that values which are too high
+ or too low seem to prevent any interrupts from occurring, and thereby lock
+ up the machine. I have found that 2 is a good number, but throughput may
+ be increased by changing this value to values which are close to 2.
+ Please let me know if you try any different values.
+ [*****Now a runtime option*****]
+
+ RESELECTION: This is no longer an option, since I gave up trying to
+ implement it in version 4.x of this driver. It did not improve
+ performance at all and made the driver unstable (because I never found one
+ of the two race conditions which were introduced by the multiple
+ outstanding command code). The instability seems a very high price to pay
+ just so that you don't have to wait for the tape to rewind. If you want
+ this feature implemented, send me patches. I'll be happy to send a copy
+ of my (broken) driver to anyone who would like to see a copy.

+Persistent DMA Buffers:
+
+The sound modules normally allocate DMA buffers during open() and
+deallocate them during close(). Linux can often have problems allocating
+DMA buffers for ISA cards on machines with more than 16MB RAM. This is
+because ISA DMA buffers must exist below the 16MB boundry and it is quite
+possible that we can't find a large enough free block in this region after
+the machine has been running for any amount of time. The way to avoid this
+problem is to allocate the DMA buffers during module load and deallocate
+them when the module is unloaded. For this to be effective we need to load
+the sound modules right after the kernel boots, either manually or by an
+init script, and keep them around until we shut down. This is a little
+wasteful of RAM, but it guarantees that sound always works.
+
+To make the sound driver use persistent DMA buffers we need to pass the
+sound.o module a "dmabuf=1" command-line argument. This is normally done
+in /etc/conf.modules (or the more proper /etc/modules.conf) like so:
+
+options sound dmabuf=1
+
+If you have 16MB or less RAM or a PCI sound card, this is wasteful and
+unnecessary. It is possible that machine with 16MB or less RAM will find
+this option useful, but if your machine is so memory-starved that it
+cannot find a 64K block free, you will be wasting even more RAM by keeping
+the sound modules loaded and the DMA buffers allocated when they are not
+needed. The proper solution is to upgrade your RAM. But you do also have
+this improper solution as well. Use it wisely.
+
I'm afraid I know nothing about anything but my setup, being more of a
text-mode guy anyway. If you have options for other cards or other helpful
hints, send them to me, Jim Bray, jb@as220.org, http://as220.org/jb.
