The FreeBSD boot disk (of all releases mentioned above) starts up with

keyboard: no

on my new Athlon 600Mhz system on an MSI 6195 motherboard.

This is not a hardware problem, as both NT and RedHat 6.1 boot
fine on the system.
>How-To-Repeat:
Boot off any of the boot.flp images.

 What keyboard have you got, and is the keyboard enabled in your BIOS?
 
 Ciao,
 Sheldon.

 Sheldon> What keyboard have you got,
 
 I've tried a Keysonic KB 230, an old Cherry MF/2 keyboard (previously
 hooked up and working fine on another FreeBSD system), and an Olivetti
 PS/2 keyboard.  Same result everywhere.
 
 Sheldon> and is the keyboard enabled in your BIOS?
 
 Yes.

 I've found the cause: it's the timing of the keyboard probe.  When I
 set
 
 #define PROBE_MAXRETRY	500
 #define PROBE_MAXWAIT	40000
 
 in probe_keyboard.c, the keyboard gets detected.  Furthermore, I can
 install with -h.
 
 It seems to me the delay code there is going to be less and less
 likely to work with newer motherboards.

This may be fixed by some hacking around in boot2's keyboard probe code. 
Since I sort of maintain boot2, I'll take this.

 Hi,
 
 As it doesn't look like much has happened with this PR I thought I'd 
 resurrect it, so I took a look at the boot code. The commentary around 
 delay1ms() in /usr/src/sys/boot/i386/libi386/vidconsole.c has this to say:
 
 /*
   * This routine uses an inb to an unused port, the time to execute that
   * inb is approximately 1.25uS.  This value is pretty constant across
   * all CPU's and all buses, with the exception of some PCI implentations
   * that do not forward this I/O address to the ISA bus as they know it
   * is not a valid ISA bus address, those machines execute this inb in
   * 60 nS :-(.
   *
   */
 
 The unused port in question is port 0x84. (Incidentally, this is 
 #define'd in the code; the macro is used in delay7() but not in 
 delay1ms(). This should probably be corrected for neatness' sake.)
 
 I suspect the MSI 6195 is one of those boards which breaks the delay 
 routine. ;) (Strangely enough, MSI chipset works just fine with it.)
 
 There are two workarounds for this; either, as suggested, whack up 
 PROBE_MAXWAIT to about 20 times its current value, or come up with a 
 better delay routine. The only problem I can see with increasing 
 PROBE_MAXWAIT is that it may slow things down marginally when you boot 
 up a machine that doesn't have a keyboard and don't put the '-P' option 
 into 'boot.conf'. A better delay routine might be neater but is beyond 
 my capabilities, I'm afraid ;)
 
 Keith

 I just checked again: for whatever reason, things work fine now with
 4.6.2.  Thanks for taking a look!
