    I had the NIC running on D4000 but the EMS card ran at D000. So I changed the NIC to run at CC00. It cleared up all but two problems:
    Pine 3.96 locks up if the EMS card is running. If I disable the EMS Drivers in config.sys, then Pine runs normally.
    XFS 191 displays "Drive not ready" Status on remote Linux NFS Volumes. With or without the EMS card running. So, I can't share networked files with the Tandy, I'm not sure if the remote NFS server is the problem. It runs pcnfsd 1.6

    D000 is the XT-IDE Controller.
    E000 is the Tandy Rom.
    C000 is VGA Video I think.
    CC00 is the NIC.

    From what I can tell, only Wolf3D can actually see the EMS. No other program I have has managed to actually utilize it. I don't seem to be able to load Device Drivers into it, I don't think DeskMate can see it.

    I still need assistance fixing XFS 191 or finding alternatives.

    EMS requires 64K of memory to act as the page frame. This defaults to C000, D000, or E000 but can be overridden by the EMS driver and put at any contiguous 64K area, although aligning to a segment boundary is typical.

    You might have crammed too much into the system. Your upper memory probably looks something like this:

    A000-AFFF: VGA graphics memory
    B000-B7FF: unknown, B800-BFFF: VGA text memory
    C000-????: VGA BIOS ROM, CC00-CFFF: NIC
    D000-????: XT-IDE Universal BIOS
    E000-????:
    F000-FFFF: Tandy ROM

    Use a program like Norton sysinfo (6.0 or later), Quarterdeck Manifest, Microsoft MSD, or InfoPlus to determine the start and stop of everything above A000 and that should let you consolidate where things are located such that you can configure the EMS card where it can put its 64K page frame.

    I don't think you have any ROM at E000. That area is usually free. The Tandy TL/2 BIOS ROM is only 64K.
    Offering a bounty for:
    - The software "Overhead Express" (doesn't have to be original, can be a copy)
    - A working Sanyo MBC-775, Olivetti M24, or Logabax 1600
    - Documentation and original disks for: Panasonic Sr. Partner, Zenith Z-160 series
    - Music Construction Set, IBM Music Feature edition (has red sticker on front stating IBM Music Feature)

    I have used MSD and a program called PC-config. GlitchWorks was the one to configure the card to Co-exist with the Hardle XT-IDE. (My Cousin burned out an IC on the card once and GlitchWorks had to repair it.)

    I want to restore Maximum possible functionality to the Tandy. This means:
    The Tandy should be able to Check E-mail from my Internal DoveCot IMAP Server I have setup. (The POP2 Services it did use are long gone)
    I'd like to be able to Use NNTP with it again, by some means.
    I want to be able to use NFS again.

    I'll power on my 1000TL this evening I have basically an identical setup to you, with a LoTech 2MB EMS card. Mine has not had any issues. I have it packed away since we're in the process of moving. I actually just telnet into a raspberry pi zero w for alpine/slrn/lynx and and tell myself it's an isp shell account, my EMS memory is used mostly for drdos TASKMGR memory, so I can do basic multitasking.
