    I didn't buy the Z87 for XP compatibility. I bought it before I even started using XP regularly. It was inexpensive and had what I needed for 9x. I have the I7-4770 CPU. For Math, the FX8350 is significantly faster. If I want to got further I will get a ThreadRipper.

    The 1152MB limit is due to Kernel Memory Database issues. It is separate from the VCACHE issue. Unlike the VCACHE issue, this cannot be fixed without Patching. I described the VCACHE issue in some detail recently in another post. It can occur if you exceed around 768MB of RAM. Video drivers can make a significant difference depending on how they handle Video Memory management. Microsoft set the Maximum File Cache to 800MiB, which is too large. My RAM Limitation Patch sets the default Maximum File Cache to 512MB or to a User specified Value. It can also be set by adding a MaxFileCache entry into SYSTEM.INI. The XENO86 Patch sets it to 512MB.

    It behaved as expected. You need my Patch to use more RAM.

    The i5-2500K only four Threads. I have eight. It would have taken almost twice as long to do those computations.

    Without Patching you cannot exceed approx 1152MiB of "available" RAM in Windows 98/98SE period. The limit for ME is around 1.9GB. PAE requires restructuring the Page Tables. This would require a major rewrite of the Kernel memory Routines and all Drivers that need to see Physical Memory. I use PSE in my MEMORY64 API which is more compatible with the existing Page Tables.

    When I first saw USB 2 Headers listed in the Specification for that Motherboard, I assumed that they would support EHCI and be compatible with 9x. I now know that they are connected to a USB 3 Controller even if they only support USB 1 and 2. MrMateczko sent me a SCANPCI dump that proved it. A XHCI Driver is still needed to use them. A similar thing happened with USB 1 and 2. The early USB 2 Controllers had a separate USB 1 Controller in parallel, so you could still use the ports as USB 1 in Windows 95. Newer Controllers only have one programmable Controller so now USB 2 Ports cannot be used in standard Windows 95 period, even though they support USB 1 Devices.

    I have encountered a reliability issue with USB Networking. USB Sound is very simple and reliable. For a Z170, as it stands now, I would go for a PCI USB Card and a PCI SATA Card.

    Trying to solve too many problems at the same time on the same machines is not productive.

    Free/cheap is always nice, start coding.

    I don't think XP would be considered a "Modern" OS. I used to use Windows 10 to handle a couple of Websites that didn't work in Chrome 49. Now I know I can access them in 98SE with the K-Meleon Browser. I haven't booted anything later than XP in months. Windows 9x may be tied to one Core, not necessarily the Base Core, but I have an API to utilize the other Cores.

    It would be hard for me to work my "Magic" when I cannot see a problem on any of my Machines. My M5A97 and my Sli Krait are both AMD970 Motherboards using nVidia 7xxx Video Cards.

    No PCI changes. It sounds like there are some BIOS and/or Hardware issues with the Asmedia Controller. Hopefully they can fix it.

    When I tested it, the BSOD seems to be dismissible without problems. There doesn't seem to be a limit set. It just overruns a table. I would have to identify the code that creates the entry and determine how to make it fail gracefully.

    I was able to open 87 DOS Boxes by Patching VCOND.VXD, but several System Programs and Functions only expect 64 DOS Boxes maximum so having more causes problems. It was fun while it lasted.

    Standard GPT disks would be ignored by Windows 9x. Hybrid or my Mixed GPT and MBR disks may not.

    The Graphics Card does not necessarily tie up 256MiB of System Arena space. It depends upon how the Graphics Memory is managed. The Graphics Memory is distinct Physical Memory. It only ties up System Arena space when it is mapped into Virtual Memory for manipulation by Windows. When I first developed my RAM Limitation Patch, I noticed that my 128MiB ATI Card DID grab 128MiB of System Arena space. The Driver apparently mapped all of the Video Card Memory into Virtual Memory. I designed the /A Option on my RAM Limitation Patch to force the allocation of the Video Virtual Memory to go to the Shared Arena rather than the System Arena. There is generally a lot more Shared Arena space than System Arena space. I thought that the newer 256MiB and 512MiB Video Cards would cause serious problems, but when I tested them, I saw that the Drivers no longer allocated large blocks of System Arena space and my /A Option was not needed. Apparently they realized that mapping the entire Video Memory would cause serious problems and developed a different strategy to handle it. Your System apparently allocated 800MiB to File Cache and around 189-192MiB to everything else.

    Not disagreeing. Of course breaking the limit is always fun.

    256MB is the maximum amount of space that can be used by DOS Boxes. The System Arena is 1024MiB. I said you used 96.5% of the System Arena Space. Your 8 DOS Boxes used up the rest. The vast majority of the space got locked up by the File Cache. By default, it uses some percentage of the available RAM up to an absolute limit of 800MiB. Needless to say, you can't get 64 DOS Boxes without reducing File Cache as 800MiB + 256MiB > 1024MiB. This doesn't even consider the rest of the Operating System. @jaclaz I have locked Icons for 6 DOS Boxes. On occasion I have used even more. 64 may be a bit much, but I already have a clue on how I might be able to raise that limit. The BSOD was very informative.

    I've never had a problem with DirectX 9.0c. It sounds like your Installer failed. There may be some prerequisite updates needed.

    If you don't remove the ACPI Device from Device Manager, it will not reinstall ACPI.SYS, it will just fail. SP3.CAB is part of U98SESP3, not part of Windows 9x. This is not Windows XP.

    AHCIBIOS and CDs: I checked further. AHCIBIOS should not affect CD Drivers. I don't use DOS Drivers for CDs only Windows. In DOS you would not use AHCIBIOS. I believe there is an AHCI CDROM Driver. Conroe SATA: The SATA Controller conflicts with what appears to be a nonexistent Secondary PATA Controller. I assume you have a single PATA Connector on the Motherboard. Change the setting for the "Standard Dual PCI IDE Controller" to "Primary Only". nVidia Bugs: I don't have a list. Besides the ones you have seen there is a problem with uninstallation leaving behind stuff. Tinkering with the nVidia BIOS can brick the Card. Many people have used 82.69 and my Patch successfully with the 7950GT. I have. Why would I put a warning not to use it? 1000 MT: It did appear in this SCANPCI dump. It is the last entry. I think you clipped it off in your previous dump. Why would I want to spend money for an old NIC Card when I have plenty of newer ones. My Patches aren't even about NIC Cards. One Patch happens to help with a problem caused by NIC Cards. Installing a NIC Card does not refresh ESDI_506.PDR. U98SESP3 replaces it. My Patch modifies it. nVidia BIOS Patch: If you flash the nVidia BIOS, you do not need to use the main NVCORE Patch. It does not hurt to use both. I suggested that you unpatch NVCORE as a test since you claimed the Patch was causing problems. The PCI Patch may still be needed. I wouldn't worry about the Interrupt Fix for now since you obviously aren't using it now. AMD970: Motherboard idiosyncrasies are always possible. I have seen plenty of them. DMA: There should be a Disk Device for any SD Card or other Disk that is actually present. An SD card probably would be slower even with DMA enabled. You could try setting them from Safe Mode.

    I disabled the Streaming Proxy as well as all of the others except the 3 I mentioned before. Still had Sound.

    Another unexpected Driver. What is VCLONE.MPD? Try removing/renaming it and ignoring any missing File Warnings.
  24. rloew
    256MiB of precious System Arena space. I didn't measure the amount of total space used. File Cache permanently reserves System Arena space, even if it is flushed from Physical RAM. The 64 DOS Box limit is hard coded. The 65th DOS Box crashes due to a Table overrun
  25. rloew
    I ran an experiment to see how much space a DOS Box uses. At 4100KiB each, your System Arena was approx 96.5% full. I underestimated the memory usage of a DOS Box before.
