OK. This is what happens during Bochs' boot of the disk image with what I see happening in UniPCemu written after each line and below (if something isn't in the Bochs log):

Now trying the build 1381 CHK version...

It says "2 System processors", although the normal installer didn't do that until the first boot?

Then:

1INIT: \SystemRoot => \ArchName\multi(0)disk(0)cdrom(159)\i386

Then a lot of information on mounted volumes (listing various drive letters).
And starting the installer...
Edit: Currently copying over the files for the GUI part of installation...
Edit: 2:22 hours later, 24% copying the files. This is probably going to take all night at this rate(about ). I'll check again once it finishes.
So about 9 hours and 51 minutes to copy the first stage over to the disk (not including formatting the disk, which will make it take even longer. Reusing the previous NTFS partition here (from the non-booting Windows NT 4.0 workstation in it's first phase complete state)).

OK. NT4's checked build displays some mounting information during boot(all floppy, CD-ROM and hard disk mount paths).
Then chkdsk output(nothing special, just as run with modern OSes).
Then pagefile 10-64MB (512MB RAM) at \??\C:\pagefile.sys with a size of [15..60] MB
Then it enters GUI mode, with the version displayed at the top of the screen.
Then the usual reboot by 8042 after some HDD activity writes and reads.
Edit: Still nothing is logged, not even in the checked build? No EVT files to view are created with infirmation why it happens. Nothing at all?

There is a pagefile though, but I doubt that can be used in some way?

OK. Now I'm trying the /CRASHDEBUG option with Windows NT 4.0 on UniPCemu (although it's still the CHK build I'm running).

Used the Bochs completed installation to modify the boot.ini file after removing it's attributes(System, Hidden, Read-only).

Edit: I then copied the CHK's DEBUG folder to the Windows 95-C(OSR 2.5) Dosbox SVN Daum image. (although running on Dosbox X with the serial port (COM2) in "nullmodem server:UNIPCEMUIP port:UNIPCEMUPORT" mode.
The Dosbox software seems to successfully connect to the UniPCemu that's in serial passthrough mode with the necessary Dosbox serial nullmodem protocol enabled.

So now I've gotten a Dosbox Windows 95 instance that should (theoretically) be able to connect to the Windows NT 4.0 instance (assuming Dosbox doesn't crash or hang during it). And Bochs can take care of modifying the Windows NT 4.0 NTFS filesystem files required for changing settings to make UniPCemu boot into (like /CRASHDEBUG etc.).

Although /CRASHDEBUG might not be enough in this case.
Edit: i386kd won't run on Windows 95 it seems? Missing DLL files. Probably NT 4.0 DLL files?

OK. Now, with UniPCemu's latest commits it can connect to a physical/emulated serial port, providing one serial port for each instance launched as a Dosbox-compatible TCP port, which is in Nullmodem mode with RTS/CTS and DTR/DSR passthrough enabled.

So now, running UniPCemu in that mode, where it's connected using TCP with UniPCemu running it's serial port in Nullmodem mode, which is in turn running Windows NT 4.0 with debugger enabled.
Then the UniPCemu instance running as a server(the first, not the one running Windows NT 4.0) is connected to an emulated COM port, which is in face the COM0COM driver running at a COM port less than #10.
The other end on the COM0COM driver port is another emulated COM port, which is also exposed to Windows 10(both are, which one being connected to UniPCemu's inputs/outputs). The other COM port that's in the COM0COM pair is then connected to using the NT 4.0 CHK build's i386kd app.

Now, i386kd displays the NT 4.0 information and kernel debugging information at least. Although I can't see if the NT 4.0 is actually in debugger mode, I do see the UniPCemu instance connected to the virtual COM0COM port having it's DTR and RTS lines raised (connected to the emulated DSR/CD and CTS in Windows NT 4.0).
I think I also saw some data being transferred between the two instances (through the COM0COM connected UniPCemu being debugged).

Although to make it connect to the serial port, I simply modified the serial modem code in the Dosbox-compatible nullmodem emulation with some calls to the Dosbox's libserial code. Then modified the libserial file to work with UniPCemu's system (memory allocation, some little typedef modifications and merging in it's headers. Although it says it also supports OS2(untested), that isn't supported by UniPCemu (not likely it will in the future, since it's too old to run UniPCemu on).

The current end result is as follows:
i386kd <=COM4=> COM0COM UART <=COM5=> UniPCemu TCP server <=TCP connection=> UniPCemu running NT 4.0

Just adjusted the UART and connection speed a bit. Now:
- The packet server stays at a connection speed of 57600 BPS.
- The serial port connection on the host machine can have it's speed set to any integer number using a setting in the configuration file. Setting it to 0 sets it to 57600 BPS.
- The emulated serial connection will poll and send at the speed configured by the UART that's emulated (in BPS, rounded down).

Just modified the speed of the outgoing and incoming TCP connection a bit:
- All modem-to-modem and TCP-to-packet server communication is using 8 cycle setting (8 cycles to send/receive a byte) for sending/receiving.
- All speeds between modems are configurable in the settings.
- The speed for a nullmodem configuration is still determined by the UART instead.

The CONNECT message of the modem now reports said speed in baud (in the settings file). The number version (when the modem is configured to do so by software) of that still always reports a 57600 baud rate, due to it being less flexible in available values.

OK. The CONNECT messages have been improved somewhat.

The NT 4.0 workstation debugger should connect correctly using COM0COM for a virtual port for the UniPCemu server to connect to (it converts the COM0COM serial port into a TCP port, which is connected to UniPCemu running WIndows NT 4.0 workstation, which is in the same nullmodem mode).
NT4.0 workstation itself is configured to use the emulated modem port, which is configured in nullmodem mode (and connected to the server build through the TCP nullmodem connection).

So theoretically, the i386kd debugger should see the NT 4.0 going online?

Edit: Hmmm... In NT 4.0, perhaps the page fault at C1140000 is part of the issue?
Edit: OK. Made my own mistake on the copying the current version to the server folder I use for testing the passthrough and packet server.
Managed to configure the whole thing, then wondering why the input lines from the virtual COM port never changed, even though the software on Windows 10 was running...
Then I remembered that I forgot to setup the required setting for the port to actually be used (otherwise, it'll just take it's inputs from the emulated system and not use the physical/virtual serial port at all)... Whoops 😖

Edit: The debugger connection at least seems to be working properly. I've made it set a breakpoint on c1140000 (BP0 c1140000) and then gave the go instruction ('g') to make it go and run the remainder of the boot process.

I do see the HAL dumping all supported bus ranges in the debugger... 🤣

But at least the debugger is running properly now, having control over the machine I hope (don't see anything special yet).
Edit: Hmmm... SOme VideoPortInitialize unfreed stuff is being dumped. AS well as some "0:IoReportResourceUsage: Bad resource list being translated" and "0:IoTranslateResourceList: address could not be translated". Those 'unfreed address' by the 0:VideoPortInitialize say "f2375000", physical c0000 size 40000 and 3b0 size 0000000c?
Edit: Interesting! Io port conflicts "in Driver et4000" are showing up?

OK. Reached the reboot point. That happens at 0008:80008558 (the OUT instruction to the 8042).
The previous executed instruction was at 0008:80008554. That could theoretically be used as a breakpoint to verify what's happening (partly).

The debugger in Windows 10 otoh dumped a lot of very interesting information:

OK. Doing a quick Google on that LDR: Using CriticalSectionTimeout leads me to this: private/ntos/dll/ldrinit.c#L731
Somewhere inside the WIndows NT 4.0 kernel that is (don't know if it's allowed to post the full link here, even though it's an indefencible leak apparently, so removed the base of the url itself).

It's trying to load some DLL afterwards? Some function named "LdrpInitializeProcess"?

Isn't that "\system\setup" key supposed to be "HKEY_LOCAL_MACHINE\system\setup"?

Hmmm... C1140000 seems to be opcode C7h(MOV modr/m32,reg) at address 803ab33b.
But that's during the text-mode part of booting?

Just optimized the handling of the debug registers a bit to check for breakpoints being active or not a bit faster(optimized for them not being active of course) by reducing multiple variables(4 byte variables, 1 for each breakpoint register) to only 1 byte to easily check if they're to be checked at all.

Just tried WinCheckit 5.0 on Windows 95 C(OSR 2.5).
The CD-ROM read sector test seems to hang. Then trying to quit the program it asks to save a dump of collected data(registry etc.).
Then, trying to make it save that data makes Windows 95(?) report that the registry is corrupted? And trying to restore it from a backup as it calls it fails, giving the only option to shutdown Windows?

So something is going terribly wrong there.

Hmmm... Managed to get PCI IDE working once again on the i430fx. Now it has some weird problem with trying DMA transfers without properly setting the DMA command register to actually transfer it to use ATA busmastering DMA (next problem)?
Edit: Hmmm... I do see it write FFh to FFFC immediately before entering a loop waiting for the IRQ after executing the C8 read DMA command on the HDD?
Edit: It somehow seems to assume the DMA controller for the primary channel is at FFFC?

Yeah these latest changes have broken booting for me (cdrom0 or hdd0, with Bochs BIOS).
I went back to commit a3371a63 and that one seems to work, but some minor patching is needed for Linux:

libserial.h: "termios backup" should be "struct termios backup" maybe?
libserial.c: some #ifdef trouble, as there are messages about undefined refs to SERIAL_xxx functions.
It seems LINUX is not defined, so need to use IS_LINUX instead?

The compiler also doesn't like the last parameter or tcsetattr() on line 312:
&port->backup should probably be &((*port)->backup) or something like that.

Yeah, on the latest commits I'm trying to seperate the PCI IDE card from the onboard i430fx/i440fx chipsets. Runs fine on the i440fx(enabled by BIOS), but the i430fx rejects the card and enables onboard PIIX instead, which has no mounts currently. The two disk mounts are now always on the PCI IDE controller instead of onboard.
Onboard is also improved for the 85C496 chipset, which is an alternative to the i430fx/i440fx PIIX, which are both hardcoded to legacy IRQs and ports (BARs always zeroed pn i440fx).
Edit: Hmmm... Lots of errors on Ubuntu 20 now?
Edit: Just fixed the build on Ubuntu. It properly compiles now!

It doesn't look like the Bochs BIOS supports PCI IDE devices? UniPCemu has it implemented as documented by the PCI IDE spec at osdev.org's documentation for the PCI IDE (as well as the documentation for the relevant device, see the PCI IDE spec rev 1.0).

The PCI BARs should now only be active when in PCI native mode. In legacy mode they're disabled and forced to legacy ports and IRQs.

The BARs are still writeable though, and respond like a PCI device (when read back).

The i430fx still leaves the device disabled for some reason? It's in legacy mode by default (as documented for PCI IDE rev 1.0 spec), but since the card is disabled, it's not running and booting on the i430fx?

Just fixed the Bochs BIOS.

I've modified the PCI device to disable the PCI BARs when in legacy mode again.
I've also forced the i430fx/i440fx PIIX IDE in legacy mode, but with only the IRQs in legacy mode (the I/O ports are in PCI mode).
The i440fx BARs are still zeroed, except BAR4. The i430fx BAR0-3 are still changable.

The Bochs BIOS now properly detects the hard drives again. It even configures the PCI properly.
The i430fx BIOS I use still has issues (the S728P.ROM one).
