[comp.sys.att] PC6300 Clock problem...

turnerk@boulder.Colorado.EDU (PUT YOUR NAME HERE) (09/11/90)

	I own an AT&T PC6300 and have a problem with my clock.  With the version of dos that came with the computer everything worked fine.  I have since upgraded to MS-DOS V3.3.  Now the clock does not keep time when the computer is turned off.  Is there a special driver I need or did the battery just mysteriosly go dead when I switched dos versions.
		Thanks for you info...

The DOS 2.11 that comes with the 6300 includes a built-in clock driver
that understands the hardware clock.  If you upgrade, you need to use
an installable driver.  AT&T includes one with their DOS 3.3, but I have
seen public domain drivers on a number of different BBS systems.

Someone has probably told you this already but you need AT&T's DOS 3.3 for 
the clock to run correctly.  I tried to use regular DOS 3.3 on both a 6300 and
on a 6386 and needed to get AT&T's version.  This also applies to DOS 4.01.

There is at least one driver that will mate the 6300 clock chip with generic
versions of DOS.  One that I have heard of (but have not used) is archived as
clock90s.zip on the AT&T support BBS (201-769-6397).  Another claim for this
driver is that it will keep correct time for 1992 and beyond when even the
AT&T versions of DOS will be at a loss for the right time.  The documentation
for this package has the technical explanations why this is all true.
