When running Windows 95 A in UniPCemu I get a #GP fault at 117:6522 when Initializing the kernel(according to bootlog.txt).

It's executing a mov segreg,reg instruction at said location, which faults.

Anyone knows or can lookup(using their own emulator) what value it's supposed to load at said location during Windows 95 A booting? Is it supposed to fault at said location?

Windows 95 is running on a basic Compaq Deskpro 386 with all Dosbox-compatible(e.g. all hardware but the Gravis) hardware enabled at their default IRQs(see UniPCemu's manual for the IRQ assignments) installed with VGA graphics.

Anyone? Is it supposed to fault at said location?
Edit: It's a RETF trying to return to address ECC4:BFFBB368.

CR3 is 2f2000. TR and it's base is 0x18 and c000aebc.
Edit: The LDTR is at 80009c00, limit 1fff.
Edit: Hmmm... The invalid segment is located at physical memory location 153210. SS has a base of 0? Does that mean anything? (And a small non-4G limit)

Edit: Hmmmm... Perhaps the offset BFFBB368 is a hint at what it's trying to do with the kernl? Anyone?
Edit: Hmmmm. I see it being read from the hard disk many times, but that shouldn't be the issue...

Edit: I see the value being calculated from an ADD EAX(6524),dword DS:[12FC]?

DS:12FC contains 87A0 there?

Further up, at 0117:00006a35, said value is stored as a result of some function it seems?

Said function seems to start at 0117:00006a32.
Edit: Hmmmm... It seems to be looking at the LDT for the process? The value that's added seems to be the code segment's base address' low 16-bits?

It doesn't look like it's reading it's memory, is it?

Edit: Just went through the code for said instruction at boot. It properly reads it's data from memory, so why doesn't it log? Hmmm...

Strange. Looking at the row being logged for the very first "0117:00004a96 83 3E 32 12 00 cmp word ds:[1232],0000" instruction shows that it IS being logged? Perhaps an repeating issue?

Edit: It was trying to log it, but the buffer was too small to properly log the immediate(printf-ed version, as well as their converted line endings(which doubles the size of each line endings converting them to CRLF format from CR or LF). So the buffers that stored them were increased quite a bit for a much larger buffer.

I've increased the raw logging buffers(for one single line to log, this applies to both the raw sprintf input-parsing buffer and the output ) from 8K to 512K(with the debugger buffers to log staying 256K for the entire log entry(1000 memory access entries) and 256 bytes for one memory access). Of course the CRLF conversion buffer is double that(since any line break can be converted to at most twice the size(CRLF/CR/LF->CRLF conversion).

So now, there's a 256 byte memory access buffer(should be more than enough to contain any memory access), a 256K cycle-memory access buffer(for all memory accesses by the 256 memory access buffer, for up to 1000 memory accesses(actually an entry takes 256 at most, with added "; " delimiters adding to each one of them), so a bit less, 2 characters more, so 258 bytes per memory access(except the first one, which is 256 bytes at most)). Then said buffer is passed to the logging function, which sprintf's it into a 512K buffer. Then it converts said line breaks from that buffer and puts the result in the 1MB buffer for actual writing to stdout, comparision against stdin and writing to the log file(together with a up to 256 bytes timestamp(which uses it's own buffer or that, so no extra space in the 1MB buffer is needed), if enabled for said logging functionality).

Here's the new logs with the fixed buffer sizes(as mentioned in the above post):

Filename: debugger_segment117_Windows95BSOD_improvedbuffers.7z
File size: 1.69 MiB
Downloads: 32 downloads
File comment: Fixed buffer size logs of Windows 95 running segment 117h.
File license: Fair use/fair dealing exception

Edit: Although this is Windows 95 in Safe mode instead of Normal mode.
It now tries to return to segment FAE4 instead of CEE4.

Edit: Interesingly, the return address is taken from BFF71000+(3(EBX)*4). So the 3rd dword entry for the page mapped at BFF71000. Perhaps BFF71000 is a hint at which process it's trying to RETFD to?
