Brian, 3ds Ver 4 is crashing during the rendering process. It leaves a message at the Dos prompt, "Memory Protection Fault, CS:EIP=000FH:0010B5B5H" (the last nine alpha-numerics are always different). I've had this happen on both stand alone systems and now on my Lantastic net, as well as WFW. Microsoft Dos tech support is unfamiliar with this memory address, which leads me to believe it is Pharlap related. The crash usually occurs when rendering between frame 1 to 50, file size doesn't matter. The problem occassionally occurs when just running the program also. It happens on any machine on the net. Can you help me isolate this as a Pharlap memory addressing problem, or direct me a new direction? Thanks

<<"Memory Protection Fault, CS:EIP=000FH:0010B5B5H">> Memory protection faults are almost always the result of a memory conflict. below are some instructions to help you isolate and identify that conflict. -brian Title: Clean system boot; diagnostics for memory conflict… Description: To confirm that the problem is caused by a memory conflict, re-start the computer with simplified settings (a 'stripped system') and see if the problem goes away. For DOS-only computers, a stripped system means that the computer is rebooted without terminate and stay resident (TSR) programs nor device drivers that are not absolutely necessary for the operation of the operating system and computer. The Autodesk program should also be configured for VGA display if possible, to rule out display driver conflicts. To reboot into a stripped system for 3D Studio and Animator Pro, change the system files as follows: CONFIG.SYS should contain only: FILES=40 BUFFERS=20 AUTOEXEC.BAT should contain only: PATH=<your path> PROMPT=<your prompt> You may want to use the DOS SYS command to create a bootable floppy for this trouble-shooting exercise and place these simplified system files on the diskette. Or, you may edit the existing CONFIG.SYS and AUTOEXEC.BAT files currently on the hard disk (make back-up copies first). Make sure you have a bootable DOS floppy on hand, just in case the computer has trouble rebooting. Note: Quarterdeck QEMM users may find it helpful to review the QEMM trouble-shooting documentation and use the Analyze utility to track down memory conflicts. Trouble-shooting: If the program now operates correctly, the next step is to determine which program or driver in your system files is causing the conflict. Edit the CONFIG.SYS and AUTOEXEC.BAT files, adding one device driver or TSR command at a time, rebooting, and starting 3D Studio/AAPRO until the error reappears. When the error happens, the last item you added to the configuration is probably the trouble maker. Once we know which drivers are conflicting, we can determine the proper course of action. If you are using special display adapters (for example, a Targa frame buffer), you should check the documentation that came with the display driver to see if special memory settings or EMS exclusions are needed.

Brian, A guru told me to put a /s after the cd-rom driver. Something to do with the ms-version being written for networks. Rick

<<A guru told me to put a /s after the cd-rom driver. Something to do with the ms-version being written for networks.>> The /s paramater stands for SHARE and allows other users on the network (if peer to peer) to access your CD-ROM. -Brian

Brian, My machine exactly. I think it may be the type of simm. I replaced a single sided simm with a double-sided simm – it's been blazing all da day. I'm running an ASUS 100MHZ/P5 with 16meg. The single sided simm has two chip outboard on either end with a encoder chip(s) in the middle. Pop the top and take a look. I hope that's it. Let me know. I also posted mess# 165669 to Richard Turnock(same problem). Good Luck, Chris Martin
