+IMHO it's easier to use "make install" for linux and hack /sbin/installkernel

+You need a fixed readprofile command for 2.5 ... either get hold of
+a current version from:
+http://www.kernel.org/pub/linux/utils/util-linux/
+or get readprofile binary fixed for 2.5 / akpm's 2.5 patch from 
+ftp://ftp.kernel.org/pub/linux/kernel/people/mbligh/tools/readprofile/

+Add "profile=2" to the kernel command line.

- * 360k/720k disk support: Andrzej Krzysztofowicz <ankry@green.mif.pg.gda.pl>
+ *	gutted by H. Peter Anvin (Jan 2003)
  *
  * BIG FAT NOTE: We're in real mode using 64k segments.  Therefore segment
  * addresses must be multiplied by 16 to obtain their respective linear
  * addresses. To avoid confusion, linear addresses are written using leading
  * hex while segment addresses are written as segment:offset.
  *
- * bde - should not jump blindly, there may be systems with only 512K low
- * memory.  Use int 0x12 to get the top of memory, etc.
- *
- * It then loads 'setup' directly after itself (0x90200), and the system
- * at 0x10000, using BIOS interrupts. 
- *
- * NOTE! currently system is at most (8*65536-4096) bytes long. This should 
- * be no problem, even in the future. I want to keep it simple. This 508 kB
- * kernel size should be enough, especially as this doesn't contain the
- * buffer cache as in minix (and especially now that the kernel is 
- * compressed :-)
- *
- * The loader has been made as simple as possible, and continuous
- * read errors will result in a unbreakable loop. Reboot by hand. It
- * loads pretty fast by getting whole tracks at a time whenever possible.

- *
- *    - Existing ISDN HiSax driver provides all the smarts
- *    - it compiles, runs, talks to an isolated phone switch, connects
- *      to a Cisco, pings go through
- *    - AMD 7930 support only (no DBRI yet)
- *    - no US NI-1 support (may not work on US phone system - untested)
- *    - periodic packet loss, apparently due to lost interrupts
- *    - ISDN sometimes freezes, requiring reboot before it will work again
- *
- * The code is unreliable enough to be consider alpha
- *
- * This file is (c) under GNU General Public License
- *
- * Advanced Micro Devices' Am79C30A is an ISDN/audio chip used in the
- * SparcStation 1+.  The chip provides microphone and speaker interfaces
- * which provide mono-channel audio at 8K samples per second via either
- * 8-bit A-law or 8-bit mu-law encoding.  Also, the chip features an
- * ISDN BRI Line Interface Unit (LIU), I.430 S/T physical interface,
- * which performs basic D channel LAPD processing and provides raw
- * B channel data.  The digital audio channel, the two ISDN B channels,
- * and two 64 Kbps channels to the microprocessor are all interconnected
- * via a multiplexer.
- *
- * This driver interfaces to the Linux HiSax ISDN driver, which performs
- * all high-level Q.921 and Q.931 ISDN functions.  The file is not
- * itself a hardware driver; rather it uses functions exported by
- * the AMD7930 driver in the sparcaudio subsystem (drivers/sbus/audio),
- * allowing the chip to be simultaneously used for both audio and ISDN data.
- * The hardware driver does _no_ buffering, but provides several callbacks
- * which are called during interrupt service and should therefore run quickly.
- *
- * D channel transmission is performed by passing the hardware driver the
- * address and size of an skb's data area, then waiting for a callback
- * to signal successful transmission of the packet.  A task is then
- * queued to notify the HiSax driver that another packet may be transmitted.
- *
- * D channel reception is quite simple, mainly because of:
- *   1) the slow speed of the D channel - 16 kbps, and
- *   2) the presence of an 8- or 32-byte (depending on chip version) FIFO
- *      to buffer the D channel data on the chip
- * Worst case scenario of back-to-back packets with the 8 byte buffer
- * at 16 kbps yields an service time of 4 ms - long enough to preclude
- * the need for fancy buffering.  We queue a background task that copies
- * data out of the receive buffer into an skb, and the hardware driver
- * simply does nothing until we're done with the receive buffer and
- * reset it for a new packet.
- *
- * B channel processing is more complex, because of:
- *   1) the faster speed - 64 kbps,
- *   2) the lack of any on-chip buffering (it interrupts for every byte), and
- *   3) the lack of any chip support for HDLC encapsulation
- *
- * The HiSax driver can put each B channel into one of three modes -
- * L1_MODE_NULL (channel disabled), L1_MODE_TRANS (transparent data relay),
- * and L1_MODE_HDLC (HDLC encapsulation by low-level driver).
- * L1_MODE_HDLC is the most common, used for almost all "pure" digital
- * data sessions.  L1_MODE_TRANS is used for ISDN audio.
- *
- * HDLC B channel transmission is performed via a large buffer into
- * which the skb is copied while performing HDLC bit-stuffing.  A CRC
- * is computed and attached to the end of the buffer, which is then
- * passed to the low-level routines for raw transmission.  Once
- * transmission is complete, the hardware driver is set to enter HDLC
- * idle by successive transmission of mark (all 1) bytes, waiting for
- * the ISDN driver to prepare another packet for transmission and
- * deliver it.
- *
- * HDLC B channel reception is performed via an X-byte ring buffer
- * divided into N sections of X/N bytes each.  Defaults: X=256 bytes, N=4.
- * As the hardware driver notifies us that each section is full, we
- * hand it the next section and schedule a background task to peruse
- * the received section, bit-by-bit, with an HDLC decoder.  As
- * packets are detected, they are copied into a large buffer while
- * decoding HDLC bit-stuffing.  The ending CRC is verified, and if
- * it is correct, we alloc a new skb of the correct length (which we
- * now know), copy the packet into it, and hand it to the upper layers.
- * Optimization: for large packets, we hand the buffer (which also
- * happens to be an skb) directly to the upper layer after an skb_trim,
- * and alloc a new large buffer for future packets, thus avoiding a copy.
- * Then we return to HDLC processing; state is saved between calls.

+KNOWN BUGS (updated March 7, 2003)
 ====================================
 1) existing symbolic links (Windows reparse points) are recognized but
 can not be created remotely. They are implemented for Samba and those that
 support the CIFS Unix extensions but Samba has a bug currently handling
 symlink text beginning with slash
 2) delete of file with read-only attribute set will fail (may be ok)
+3) mount helper syntax not quite matching man page
 
 Misc testing to do

+ * PIC AS DEVICE ZERO
+ * ------------------
+ *
+ * PIC handles PCI/X busses.  PCI/X requires that the 'bridge' (i.e. PIC)
+ * be designated as 'device 0'.   That is a departure from earlier SGI
+ * PCI bridges.  Because of that we use config space 1 to access the
+ * config space of the first actual PCI device on the bus. 
+ * Here's what the PIC manual says:
+ *
+ *     The current PCI-X bus specification now defines that the parent
+ *     hosts bus bridge (PIC for example) must be device 0 on bus 0. PIC
+ *     reduced the total number of devices from 8 to 4 and removed the
+ *     device registers and windows, now only supporting devices 0,1,2, and
+ *     3. PIC did leave all 8 configuration space windows. The reason was
+ *     there was nothing to gain by removing them. Here in lies the problem.
+ *     The device numbering we do using 0 through 3 is unrelated to the device
+ *     numbering which PCI-X requires in configuration space. In the past we
+ *     correlated Configs pace and our device space 0 <-> 0, 1 <-> 1, etc.
+ *     PCI-X requires we start a 1, not 0 and currently the PX brick
+ *     does associate our:
+ * 
+ *         device 0 with configuration space window 1,
+ *         device 1 with configuration space window 2, 
+ *         device 2 with configuration space window 3,
+ *         device 3 with configuration space window 4.
+ *
+ * The net effect is that all config space access are off-by-one with 
+ * relation to other per-slot accesses on the PIC.   
+ * Here is a table that shows some of that:
+ *
+ *                               Internal Slot#
+ *           |
+ *           |     0         1        2         3

+ *           |
