 John,

 I had forgotten some of the problems I had when I went to a 'fast' 486.
 Originially, I used 25 and 33 MHz machines and didn't have any problems
 running OS9000 attributable to hardware.  When I went to my current hardware,
 a DX-2/66, I did have many problems.  (Unfortunately, I didn't document them.)
 MW suggested I remove all caching.  I did this and things worked properly.
 Started adding caching until problems cropped up.  Turned out I couldn't
 enable 'External Cache Memory'.  BOIS is AMI.  Since you're running at 100
 MHz, you may have a similar problem.

 I have t1 and t2 in my boot file and load t3 in the startup file.  I use
 t1 for a terminal, t2 is my mouse and t3 my internal modem.  I've had no
 conflicts between t1 and t3.  I haven't tried running a modem from t1, but
 I have run the modem (t3) from a terminal on t1.  I don't remember if I had
 problems putting t3 in the boot or I just didn't get around to making a new
 boot.

 I don't remember whether earlier version of OS9000 included them but version
 1.3 includes descriptors and a driver for the DigiTech Serial card.  These
 are in the PORTS/PC8 directory.  They use the higher irqs available on
 16 bit buses.  I haven't tried them yet, but it seems they may work as
 written or with a minor modification with modem cards that permit accessing
 these irqs.

 Well, maybe.  But I think you said the printer worked properly under DOS and
 WINDOWS.  This suggests that the hardware is OK.  I'd suspect either the
 hardware's caching or the 'pcpll' driver.  I don't remember if I had problems
 with the earlier version of OS9000 but I don't with 1.3.  I go through about
 15 feet of cable and 2 printer switches (definitely not recommended).
 Several GFX programs I wrote work OK as does 'PSF'.  You mentioned (re
 serial ports) you had to remove the serial ports from the boot and load them.
 I load 'lpt2' and 'pcpll' from the startup file.  Don't remember why.
 (Sometimes I do things the 'easiest' way and don't get around to doing them
 'properly'.)

 Congratulations!  Didn't you know in this mode you are supposed to have
 bottomless pockets ?  E-mail me your mailing address and I'll send you
 a demo copy of G-WINDOWS.
