+Немного переделал драйвер звука для чипа SIS  
+
+-добавил подключение PCI устройства к контроллеру прерывания
+ (БИОС неназначил номер прерывания) назначается IRQ 5
+-изменил чтение регистра кодека (считывание и запись производится через 'семафор')
+
+в остальном оставил все как есть :)
+
+ SIS.obj - просто бинарник
+ sis.asm - исходник
+ codec.inc - (добавил номер определения своего кодека)

+ * This file holds USB constants and structures that are needed for
+ * USB device APIs.  These are used by the USB device model, which is
+ * defined in chapter 9 of the USB 2.0 specification and in the
+ * Wireless USB 1.0 (spread around).  Linux has several APIs in C that
+ * need these:
+ *
+ * - the master/host side Linux-USB kernel driver API;
+ * - the "usbfs" user space API; and
+ * - the Linux "gadget" slave/device/peripheral side driver API.
+ *
+ * USB 2.0 adds an additional "On The Go" (OTG) mode, which lets systems
+ * act either as a USB master/host or as a USB slave/device.  That means
+ * the master and slave side APIs benefit from working well together.
+ *
+ * There's also "Wireless USB", using low power short range radios for
+ * peripheral interconnection but otherwise building on the USB framework.
+ *
+ * Note all descriptors are declared '__attribute__((packed))' so that:
+ *
+ * [a] they never get padded, either internally (USB spec writers
+ *     probably handled that) or externally;
+ *
+ * [b] so that accessing bigger-than-a-bytes fields will never
+ *     generate bus errors on any platform, even when the location of
+ *     its descriptor inside a bundle isn't "naturally aligned", and
+ *
+ * [c] for consistency, removing all doubt even when it appears to
+ *     someone that the two other points are non-issues for that
+ *     particular descriptor type.

+ * @flags: I2C_M_RD is handled by all adapters.  No other flags may be
+ *	provided unless the adapter exported the relevant I2C_FUNC_*
+ *	flags through i2c_check_functionality().
+ * @len: Number of data bytes in @buf being read from or written to the
+ *	I2C slave address.  For read transactions where I2C_M_RECV_LEN
+ *	is set, the caller guarantees that this buffer can hold up to
+ *	32 bytes in addition to the initial length byte sent by the
+ *	slave (plus, if used, the SMBus PEC); and this value will be
+ *	incremented by the number of block data bytes received.
+ * @buf: The buffer into which data is read, or from which it's written.
+ *
+ * An i2c_msg is the low level representation of one segment of an I2C
+ * transaction.  It is visible to drivers in the @i2c_transfer() procedure,
+ * to userspace from i2c-dev, and to I2C adapter drivers through the
+ * @i2c_adapter.@master_xfer() method.
+ *
+ * Except when I2C "protocol mangling" is used, all I2C adapters implement
+ * the standard rules for I2C transactions.  Each transaction begins with a
+ * START.  That is followed by the slave address, and a bit encoding read
+ * versus write.  Then follow all the data bytes, possibly including a byte
+ * with SMBus PEC.  The transfer terminates with a NAK, or when all those
+ * bytes have been transferred and ACKed.  If this is the last message in a
+ * group, it is followed by a STOP.  Otherwise it is followed by the next
+ * @i2c_msg transaction segment, beginning with a (repeated) START.
+ *
+ * Alternatively, when the adapter supports I2C_FUNC_PROTOCOL_MANGLING then
+ * passing certain @flags may have changed those standard protocol behaviors.
+ * Those flags are only for use with broken/nonconforming slaves, and with
+ * adapters which are known to support the specific mangling options they
+ * need (one or more of IGNORE_NAK, NO_RD_ACK, NOSTART, and REV_DIR_ADDR).
