KURO-BOX/T4 booted and sysinst went fine.

I've got KURO-BOX/T4, which is U-boot-in-flash-ROM-already 
version of the TS-TGL, and found console was already out 
without pushing red button at power on.

I have some modifications to the src, to have
  atactl
  raidctl
  wd{2,3}*
  raid{0,1,2}
are in the MD kernel  (Attached).

I have tftp booted, with the  u-boot command
  bootp; tftp 1000000 altboot.bin; g 1000000 tftp:netbsd
and have raid setup (manually) before sysinst run. Then
installed the whole thing with sysinst onto raid partition.

The multi-user mode boots fine with
  bootp; tftp 1000000 altboot.bin; g 1000000 wd0a:netbsd

(Suprizingly enough, wd0a is not a root file system, but
just a boot partition include only /netbsd, but it 
finds correct (to me) root file system on raid1a.)

The next issue is boot from hd. I have small Linux Ext2
partition in second (but f:) partition on wd0. and
placed altboot.bin in it.

(wd0)

---------------

The u-boot command is
 setenv bootcmd1
 'sata part; ext2load sata 0:1 1000000 altboot.bin; g 1000000 wd0a:netbsd'

The first 'sata part;' is the magic word to assure some timing 
for ext2load to find sata partition.

Now everything fine. Thanks the folks here, for fantastic jobs.
Really appreciate.
