NetBSD 5.0.1 release binary distribution
>Description:
sparc/installation/floppy/disk2 binary (which is a symlink to
sparc/installation/bootfs/instfs.tgz) doesn't fit 1440KB floppy.

>How-To-Repeat:

% ftp ftp://ftp.NetBSD.org/pub/NetBSD/NetBSD-5.0.1/sparc/installation/floppy/disk2
 :
150 Opening BINARY mode data connection for 'disk2' (1528772 bytes).
100% |***********************************|  1492 KiB  102.04 KiB/s    00:00 ETA
 :
# dd if=disk2 of=/dev/rfd0a bs=36k
dd: /dev/rfd0a: end of device
41+0 records in
40+0 records out
1474560 bytes transferred in 48.477 secs (30417 bytes/sec)

>Fix:
- prepare own list file of a crunchide binary for instfs and
  remove unnecesarry binaries to shrink it
  (instfs.tgz is created from a file list for miniroot;
   see src/distrib/sparc/instfs/Makefile)
or
- switch to using ustarfs based boot floppies with RAMDISK kernel
  (I don't know reason why sparc doesn't use it)

etc?

    - switch to using ustarfs based boot floppies with RAMDISK kernel
      (I don't know reason why sparc doesn't use it)


 ustarfs is newer than sparc floppy install support.


 i think this is the best idea.

 It may require more confirmation, but there are may other bugs
 around floppy boot ;-(

 The simple workaround for overflow is building miniroot with -Os
 because instfs uses miniroot objects. Is it acceptable for 5.1?

 Build miniroot binaries for sparc with -Os to shrink instfs.tgz
 for the second boot floppy which use miniroot objects.
 This is workaround for PR install/42146, and ok'ed by mrg@.
 Don't try to read disklabel to check FS_RAID on floppy boot since
 reopening floppy could cause Data Access Exception later.
 Fixes PR port-sparc/42186, ok'ed by mrg@.
 Disable "fast trap" handlers which invoke software interrupts
 in sparc/amd7930intr.s and sparc/bsd_fdintr.s until they are
 rewritten to adapt new MI softint(9) API.
 No particular comments on PR port-sparc/42192, but
 this fixes timeout problem on floppy access on my SPARCstation 1+.
 XXX: floppy support on sun4m seems to have another problem (data overrun).
 Use /dev/fd0a rather than /dev/rfd0a to read instfs.tgz image from floppy.
 It looks newer (appearred after 1.6) gzip tries to read less than DEV_BSIZE
 (to check header?) so we can't use raw device directly.
 (note sparc bootfs ramdisk doesn't have dd(1))
 Workaround for PR port-sparc/42193, and would also fix PR install/28734.
 Explicitly clear AUXIO4M_FTC bit in FTC_FLIP macro used on
 pseudo-dma for floppy, as well as AUXIO4C_FTC bit for sun4c.
 A comment in the macro says AUXIO4M_FTC bit is auto-clear,
 but my two SS20s (including compatible) with 150MHz hyperSPARCs
 get data_overrun without it, and no bad side effect on SS5
 (works with and without this change).
 Closes PR port-sparc/42516, which is the last one of a bunch of
 floppy issue on NetBSD/sparc since NetBSD 2.0 days. See
 http://mail-index.NetBSD.org/port-sparc/2009/12/20/msg000484.html
 for details.
