Soft-ICE for NetWare Version 1.0 Readme File
------------------------------------------------------------------------------
Installing Soft-ICE
------------------------------------------------------------------------------
Soft-ICE and LDR can be loaded from either the DOS partition or the NetWare
system volume. However, this release of Soft-ICE will look only on the DOS
partition's current drive and directory for the SI.DAT file. For this reason
it is probably best to copy everything on the diskette to the DOS directory
that contains SERVER.EXE and load them from there. If the SI.DAT file is
not found, the function keys will not be initialized.
------------------------------------------------------------------------------
Soft-ICE and NLM-Check, Net-Check and NLM-Profile
------------------------------------------------------------------------------
This release of Soft-ICE will NOT run while any of the other Nu-Mega NLM's
are loaded. An error message will be displayed if this is attempted.
------------------------------------------------------------------------------
Potential problems with I/O Break Points
------------------------------------------------------------------------------
I/O Break Points (BPIO) are supported in this release, but could potentially
cause problems. Interrupts could end up being disabled for longer than they
should be. Refer to Section 3.2 (Setting Break Points) in the User Guide
for more information.
------------------------------------------------------------------------------
Hardware interrupts that overlap processor exceptions
------------------------------------------------------------------------------
Many of the hardware interrupts on the primary interrupt controller overlap
interrupt vectors for processor exceptions. To distinguish between the two
NetWare reads the 8259A In Service Register to see if a real interrupt was
pending. If the appropriate bit is not set NetWare reports a processor
exception. This can cause a problem when using the genint command or when
stepping through the keyboard handler. The problem can be circumvented by
bypassing the test in NetWare's interrupt handler.
