I am installing 3-com 3+open on a no-name clone 80486-24,VGA,colour,8MB,
,300mb disk (set up as multiple 32mb drives),mouse and 3C503 card.
The set up involves installing a server adapted version of OS/2 supplied by
3Com as the first step. This seems to work OK and it tells me to reboot the
system to bring it up under OS/2 prior to installing 3+Open.
However this boot is not sucessfull and the system stops after displaying
on screen the following:
Trap 000D
AX=201C etc
SI=000C etc
CS=04A8 etc
CSLIM=6420 etc
CSACC=9B etc
ERRCD=0000 etc
Exception in device drive A:
The system detected an internal processing error @ location #01E0:0797
The system is stopped.
I have sucessfully installed this 3+Open entry level system in a 386/25
from the same vendor.
The 486 clone runs quite happily as a DOS workstation to the 386/25
as a server.
Any suggestions would be very much appreciated !!!!

Chances are the problem is with the OS/2 Device Driver 3COM supplied to their etherlink II card. To wait for I/O programs typically attempt to flush the pre-fetch queue by a jmp $+2 (jump to the next line). The 486 is too smart. If the jump is within the pre-fetch queue it will not flush the queue and thus a jmp $+2 is much like a NOP. The new 3COM Etherlink II device driver for OS/2 does not have this problem. Perhaps 3COM will send you an OS/2 device driver update. The new device driver is included in LanMan 2.0 Hope that helps! P.S. I'm just an intern.
