Do we still need ATA disk CHS addressing?

Sorry my first reply was short, a holding reply,
	( A server died, & 2nd reserve needed time, still does )

I run 20+ assorted hosts from 4.11 to 7.2 Uni & Dual proc, i386 (real 386!)
to 686 & amd64, so I guess I'm 
  A) Pretty vulnerable to legacy scare.
  B) A litmus tesst for a wider community of others, some  with older kit, 
     not on lists or with bleeding edge latest hardware, but will 
     get hit when stuff eg HCS gets declared legacy=dumped.
	(hardware@ & arch@ are more likely mostly high enders,
	lower percentage of legacy hardware users I guess)

If I have to pull the lid on 20/25 hosts, to check disk sticky
labels, I will if I must, but could you please reccomend people
syntax to run on 4 5 6 7 RELEASES to check if a host is susceptible ?
	(Yes I know 4 is declares dead, but I still have lots of
	hosts with it &         I suspect quite a lot of others do,
	be nice to know if any of those boxes are doomed to only
	upgarde to 7 not 8 )

BTW My configs & dmesg extract:

The genuine 386 host uses config name MINI.

The config name SCAN represents a class of scanners with embedded
FreeBSD inside that a bunch of people have
I will turn on more verbose boot to increase
from its too minimal current
	ata0 at port 0x1f0-0x1f7,0x3f6 irq 14 on isa0
