>Description:
(sorry for my poor English)

1. wdcprobe() fails.
  On 386BSD, NetBSD-0.9, NetBSD-0.9a (1993/11/12 version), IDE I/F of this
  machine is probed, and BSD works fine.
  This was boot message of NetBSD-0.9a.

	wd0 at wdc0 targ 0: 203MB 684 cyl, 16 head, 38 sec (TOSHIBA MK2224FC)
	----------------------------------------------------------------
	CAUTION: character of "less than" and "greater than" are
		replaced to "(" and ")" to work around 'send-pr'
		comment treatment.
  On NetBSD-1.0 (both kcaha-10, kcbt-10), wdc0 is not probed, so I cannot
  install it. This is boot message of NetBSD-1.0.

	----------------------------------------------------------------
  And, NetBSD-1.0 works fine.

2. strange probe message of ie0.
  NetBSD-1.0 boot message says
	----------------------------------------------------------------
	ie0: unknown AT&T board type code 15
	----------------------------------------------------------------
  But, my machine doesn't have Network I/F.
  It doesn't cause problem, just FYI.

3. cursor invisible.
  This machine has DCGA (640x400) LCD display, and working on CGA compatible
  mode (I think). But, cursor is not displayed on NetBSD-1.0.

  On 386BSD, NetBSD-0.9, NetBSD-0.9a, cursor is displayed, but cursor shape 
  is strange (upper 3/4 of cursor is blinking).
  
  After applying following patch, cursor is displayed normally (lower 1/4 of
  cursor is blinking).

>How-To-Repeat:
	always
>Fix:
	Of course, this is not correct fix, only work around.

P.S.
Now, NetBSD-1.0 works fine on J3100SX, I would like to thank you this
operating system.
