I think in these machines the BIOS doesn't actually disable the ports but just doesn't mark them as being present in DOS hardware information bytes. Windows probes hardware every boot and then discovers those ports and i imagine any sort of test tools will also discover these ports. Yes, this is …

I believe that either Windows 95c is re-enabling my serial ports, or that the BIOS isn't really disabling them. Even if I disable both COM ports and use a standard serial mouse, Windows detects COM1/2 and the mouse. As such, it seems that to use the serial ISA emulator card, I must disable the …

I should have Dr. Hard installed on the HDD. Don't think I have QuickTech. SysCheck did not work in DOS either. It doesn't like the NexGen, which contains only the 386 instruction set. I think some programs are also confused CPU it is and can't run.

Interesting. I may have a system-specific problem or some goofed up software/OS. A lot of software doesn't run properly on the NexGen. What system are you using for testing? I will give this one more go with Windows 95c - plan to go into safemode and delete the COM ports, re-enable both COM ports in …

Syscheck will not run properly on my NexGen PF110. I tried it with idon.com and idoff.com Syscheck_Runtime_error_202_in_Windows.JPG When you run Windows NT 3.51, and have the emulator card setup for COM1, do you still see COM1 listed in the ports section of the Control Panel? NT is removing the COM# …

A CPU collector sent me some photos of another SXL2-66 upgrade, this time PGA-168 with VRM. This is what we're trying to replicate, minus the unnecessary extra circuitry. This adapter uses an EZ1086CM as the VRM. I have never seen one of these adapters in person or in photograph until now, so I …

Oh, I see what you mean now. I purposely did not give this a percent increase because it is not a true increase. With an ISA card, you can use a Fast cycle check point, in which you score 7.1 fps. For VLB, you must use a Normal cycle check point, and get a score of 7.2 fps. That's a whoppin' 2.4% …

Also: 386DX-40 Cycle Check Point = Normal VLB = 10346 = 7.2 fps ISA = 12192 = 6.1 fps 2.4% increase when using VLB on a 386DX It's 18% increase from ISA to VLB ;) What was your Cycle Check …

It seems to me that you do not understand the principle of operation of the adapter. When you insert it into the motherboard, it is equivalent to a COM port with a serial mouse connected to it. Of course I am aware of this. I'm not so old that I forgot such basics. It is highly unlikely that the …

Windows 95c is OSR 2.5. Previously, I tried another socket 4 system with built-in PS/2 and I couldn't get the COM1 mouse working Windows shows COM1. I spent hours trying to figure that out. Are all my Windows installations messed up? Seems unlikely to me the issue is my Windows installation. I can …

The automatic setting keeps COM1 as IRQ 4, 03F8. The RS232 ports are built into the motherboard. The motherboard is a NexGen Nx586 with PF110 CPU. The 4 others testers of the emulator card were able to leave COM1 enabled in Windows 95c? And they still have COM1 setup as IRQ 4, 3F8 in the Windows95 …

What you are suggesting is not possible on my system. I believe that enabling COM1 in Windows 95c is enabling the RS232 hardware on the motherboard and it is conflicting with the IRQ and address of the emulator card. COM1 in Windows 95c must be disabled on my system for the mouse to work. I'm not …

You must disable COM1 only in the BIOS or on the Multi i/o card. The adapter becomes the COM1 port. If you see COM1 on Windows and the adapter is installed, this COM1 is the adapter. Did you have a chance to view my screenshots in the other page of this thread? If I disable COM 1 in BIOS, Windows …
