What's New Since OS/2 for SMP 2.11
OS/2 Warp Server Version 4 Advanced provides:
High Memory Support
Memory
management has been enhanced to allow 32-bit applications to allocate and
address linear memory objects above the 512MB boundary. This effectively
breaks the 512MB memory limit in previous versions of OS/2.
Raw
File System
The Raw File System provides the
ability to access physical or logical drives using a UNC name. Since drive
access is no longer limited to available drive letters, more than 26 physical
and logical drives are now available to 32-bit applications. This allows
access to up to 128 drives without incurring the serialization overhead
of the OS/2 file system. In addition, the raw file system supports physical
disks up to 1 TB (terabyte) in size.
Enhanced File
I/O Support
With the addition of the DosListIO
function, multiple locking, unlocking, seeking, and I/O operations may
now be initiated at once. These can be synchronous (ordered) requests or,
in the case of the Raw File System, unordered requests.
MPS
1.4 Compliant Intel I/O APIC Support
OS/2 Warp
Server for SMP now recognizes multiple MPS 1.4 compliant Intel I/O Advanced
Programmable Interrupt Controllers (APICs) in a system. Multiple I/O APICs
increases the number of adapters allowed on the system.
Software
Trace Facility (STRACE)
STRACE is a tracing
tool available on Pentium-class machines which provides a software-based
timing and tracing mechanism. With the addition of the DosPerfSysCall
function, software running in ring 3 may now record events in the software
trace buffer.
Performance Monitoring
OS/2
Warp Server for SMP provides a set of functions which allow application
developers an efficient and uniform way to access system performance information
and to monitor and change processor status.
The
ICAT Debugger
The ICAT debugger is a source-level
debugger used for remotely debugging OS/2 device drivers, kernel code, Installable
File Systems (IFS), and applications running on an OS/2 Warp Server for
SMP machine from another OS/2 system.
Kernel
Debugger
The protocols necessary for communicating
with the kernel debugger over a serial communications link have been made
available for application developers.
