else has been probed. This feature could go away again, if we can curb the
problem another way.
if_ed.c, syscons.c: Set the above flag. ed# because it needs it, syscons
because it looks stupid to "detect" the display you have already filled up
with text :-)
bt742a.c: Check bt_cmd() return-val during probe, thus failing on adaptec's.
Also silenced various printf's during the probe.
isa.c: Probe devices with the above flag set before the rest. Reduce the
number of "conflict" messages per device to one.

was discovered by John Hood who also provided this fix - which is a
rewrite of the routine (and is easier to understand than the code I wrote).

Fix endless loop in siopoll() for an event on a tty with no tty struct.
Don't generate unwanted interrupts in the serial console driver. These
bugs probably don't matter unless the tty struct is dynamically allocated.
Support polled mode. To use it, leave out the irq and the vector in
the config file. It only causes extra overhead for open polled ports.
The maximum usable speed is approximately 1000 bps for a 16450 and
15000 bps for a 16550.
Other cosmetic changes.
Bug fixed, that caused system hang on first interrupt on some motherboards.
New version of PCI bus configuration code, now supports dynamic interrupt
configuration (using BIOS supplied values).
NCR SCSI and DEC Ethernet driver patched to use this feature.
*** Remove PCI IRQ specifications from your kernel config file ! ***
the first place was so that BPF could grok trailer packets. I've since
decided that this is a job for tcpdump to decipher (if at all). Also
fixed up checks for received packet length to better cope with ancient
starlan boards.

New AMD family ethernet driver. Should support BICC,NE2100, TNIC,
AT1500 and anything else that uses a Lance/PCnet type chip. Only been
tested with the BICC so far though.
Still work to do on performance and MULTICAST support needs to be added
but it's basically working and I want the revision history from this
point on

New version with improved support for WIDE SCSI using the NCR 53c825.
Test for buggy secondary cache implementations.
PCI Int to IRQ mapping now specified per slot.
This is needed for having the fdformat program no longer searching
non-public include paths.
Protect the definitions in fdreg.h against double inclusion.

most common case for this is booting a kernel that is located on
the inner cylinders of a floppy.
Also removed all occurences of spinwait(), replaced by DELAY.

First round of floppy changes. Try making `fd' more robust.
New features:
. ioctl command for setting the drive type (density etc.); restricted
to the super-user
. ioctl for getting/seting `drive options'; currently only option
is FDOPT_NORETRY: inhibit the usual retries; used when verifying
a newly formatted track
Fixes:
. function prototypes
. made all internal functions `static'
. cleaned up & corrected .h files
. restructured, to make the chaotic function sequence more rational
. compiled with -Wall, and cleared all warnings
. introduced a mirror for the (write-only) `digital output register',
to avoid the current kludge
. device probing completed by seeking/recalibrating, and looking
for track 0 being found
. holding the controller down in reset state while it is idle (and
thus saving allot of headaches)
. make requests fail that are not a multiple of the (physical)
sector size
. removed the fixed physical sector size (512 bytes), allowing for any
size the controller could handle (128/256/512/1024 bytes)
. replaced some silly messages
. fixed the TRACE* macro usage, debugging reports should be complete
now again (debugging output is HUGE! though)
. removed fd_timeout for SEEK command; seeks are always reported by
the controller to succeed, since the `success' only refers to the
controller's idea of success - there is no hardware line to tell about
the seek end (other than the `track 0' line)
. catch SENSEI's that report about a `terminated due to READY changed'
status - could happen after a controller reset
. converted ``hz / <something>'' divide operations to divisors that are
powers of two, so gcc can optimize them into shifts
. write/format operations are checked against a write-protected medium
now *prior* starting the operation
. error reports of `invalid command' and `wrong cylinder' will cause
shortcuts in the retrier() now
. fixed a bug in the retrier() causing bogus block numbers to be reported
. fdformat() does care for errors now
Known Bugs:
. no attempts have been made (yet) to improve the performance
. sometimes, bogus ``seek/recalib failed'' messages are logged; this
is still a bug in the driver, but it's not harmful since it's
usually caught by the retrier()

wider variety of systems. Include the deivers from pci_intel.c in
pci_config.c (I hope this is what was intended; my system works ok).
Use pmap_mapdev(). Automatically map any large linear frame buffers
or whatnot in VGA-style devices which ordinarily would not have their
own drivers, and don't call not_supported() for them. (This shuts up
complaints about my Matrox card.) Include the beginnings of what could
eventually become dynamically-loadable PCI devices. Allow for the
possibility of PCI devices simply providing a PCI veneer over an existing
ISA device, and shut up about them, too.
Make autoconfiguration text conform more to the style of other supported
buses.
you download the microcode to the DSP everytime you power on your system.
They provide a dos-program to do so, but no other support. This commit adds
code to the sio-driver, which implement an ioctl, which will down-load the
micro-code.
To get this functionality, you must define DSI_SOFT_MODEM.
The program to actually employ the ioctl is not included, but the entire
source looks like this:
#include <sys/ioctl.h>
#include <stdio.h>
main()
{
unsigned char buffer[100000];
int i;
read(0,buffer,100000);
if((i = ioctl(1,TIOCDSIMICROCODE,buffer)) < 0)
perror("ioctl");
return i;
}
And you use it like this:
smload < data144b.dsi > /dev/ttyid3
You need to copy the *.DSI files from the dos-media provide with your modem.
You can see what is downloaded by issuing the ATI3 command to the modem.
DSI's scheme for what code you can run on your modem isn't violated by this.

Add initialization to the if_ie driver for the Micom Interlan NI5210 card.
This is a very old 82586 based card with only 8Kb or 16Kb on board memory.
Also only 8-bit wide instead of 16-bit like the AT& or 3COM card.
Warning: this thing is only tested so far that it detects all bits
correctly but is not yet on an ethernet. Will do that tomorrow.

Update the if_ep driver for the 3C579 and bring over some of the
changes from the netbsd driver.
This is not complete: the detection of the irq in the eisa does not
work and sometimes the reset for the 3C509 in ISA in an EISA bus system
don't work ( Need a hard reset to be found again == reset knob).
DIOCGDINFO, DIOCGPART, DIOCWDINFO, DIOCSDINFO, CDIOCPLAYMSF, CDIOCRESET,
CDIOCEJECT.
CDIOCPLAYBLOCKS removed (old implementation completely wrong and I don't
know how to implement it correctly).
All routines now detects media change correctly.
DELAY_GETREPLAY increased for long time access from first track
to last.
mcd_waitrdy() now use MIN_DELAY=15 as minimal delay which independs
of machine speed.
mcd_doread() now uses real status (old code uses obsoleted soft copy of it).
clear XBSY on error in mcd_doread()
mcd_statrt(): add missing splx(s), cause dead hang with unmatched slpbio()
optimize mcd_doread(), don't set CD mode each time, keep soft copy of mode.
call getdisklabel() _after_ mcdsize() for proper sizes
mcdopen(): old code forget to set MCDREADRAW in flags when open RAW
partition, doread check it for setting RAW CD mode.
Do nothing on stray interrupt (which sometimes occurse, because driver
read data block too slow, DOS driver use 'insb' here). Old stray code
cause timeouts.
Read toc entries code rewritten to return many requested entries
(as supposed) instead of one entry with incorrect structure.
CMDREAD2 requests covered with disable_intr()/enable_intr()
(from DOS driver)
Read junk code added after read block code in doread (from DOS driver)
mcd_read_toc() code fixed to read all needed entries, old code cause
some audio tracks is not played.
mcd_playtracks() code fixed to proper check valid track range.
New binary read modes implemented (from DOS driver).

Put the printf("can't map 3c507 ram.. into an ifdef DEBUG. This will
confuse only normal users and the ie0 found/not found is sufficient.
Submitted by:
1) if_ie.c:
Changed a printf and put a space in it. Formerly the "<3C507>"
confused the syslog. He tried to see that as the priority to
log that message.
2) isa_device.h:
Changed the iobase variable from short to u_short. EISA
Adresses can go up to 0xf000 and the sign extension doesn't
look good in the probe output. Example:
ep1 at 0xffff8000-0xffff8000f is not good :-), i like more a
ep1 at 0x8000-0x8000f.
3) isa.c:
Changed a string constant from "probe" to "prob", it gets
later already an "ed" tagged on the end.
