Just tried again with the optimized version of protection checking, as well as some bugfixes on the new stack checking(it was checking offset+2 for dword accesses and offset+1 for word accesses, resulting in invalid unaligned and even limit overflowing addresses(throwing general protection faults before Windows even gets to boot at all(triple faults even, due to ESP being 0 when pushing a register on the stack)):S ).

But even with said bugfixes, the OS still crashes at the exact same location(Windows 95 OSR 2).

Just had a thought: what if I tried to install Windows NT 3.1? With 12MB of RAM that should work(on the Compaq Deskpro 386 with 12MB and a floppy-based installation)?

Currently at least got as far as formatting the hard disk(actually, the IDE controller reveals it's just reading the disk?) for NTFS. Already working in Protected mode since starting the installer.

If it runs, that will rule out problems of 16-bit/32-bit compatibility layers in Windows 95?
Edit: So far gotten up to floppy disk 2. Format is complete, somehow not NTFS(which I remember I chose), but FAT?
Edit: Disk 3...
Edit: Reached reboot...
Edit: STOP 0x0000007F is encountered? Seems to be somewhere within the ntoskrnl.exe?

Lots of more information compared to Windows 95? It's a double fault according to https://support.microsoft.com/en-us/hel ... ngle-bit-e ?

Interesting ntoskrnl.exe BSOD on Windows NT 3.1?


Edit: Interestingly, I see it invoking a INT3 single-byte instruction(byte CC) just before the blue screen? It's filtered on CPL=0 and non-real mode.

Edit: I see exception #UD on 0FA6, then single step at 0008:801bae71 to kernel 801bae82, then a page fault for access to 0023:00000000(opcode 011A at 0008:80168e00, which is ADD [edx],ebx(EDX=0)?), then a type 3 (CC) interrupt at 80102090(previous opcode was E8) to 0008:801621b0.

Anyone can defer something from this(other than the cause being ntoskrnl.exe)?

Perhaps that page fault is the cause for the BSOD? The first #UD is just CPU detection code(80486 detection like Windows 95 does).

But the [EDX] where EDX=0 is a cause for a BSOD, since it's a NULL-pointer dereference by ntoskrnl.exe(kernel mode)? So why is it doing that? Why is EDX 0?

Edit: Tried generating a log with the dumped data, but the NULL page fault happens at a different location:
CR3=30000, paging enabled.
TR=28:80203000
CS:EIP=0008:80168E00

That information should server well(ignoring the EIP part) for a simple debugger filter to find out why the NULL dereference in the NT kernel(ntoskrnl.exe) happens?

Just found a bug in the interrupt handler mechanism. When handling non-present or null descriptors(for IDT or GDT(loading CS)), it's supposed to throw a #NP fault instead of a #GP fault(as is documented in many documentations). UniPCemu throwed a #GP fault instead, which is incorrect(for emulation or loading by the OS).

Having reworked and simplified the segment descriptor loading(just checking for NULL entries, table limits and paging), Windows 95 gives a quick kernel STUB error, then the It's safe to turn off your computer screen(in orange text).

The final entry in the bootlog.txt reports:
Code: Select all
[000DC974] INITCOMPLETESUCCESS = SHELL   


Edit: It says(in text mode): "KernSTUB: Error during boot". Then immediately after that it shows the Windows "It's safe to turn off your computer" screen.

Improving and simplifying segmentation writes still makes the message occur?

Just improved gate descriptors protection checks according to the CALL instruction documentation.
Also fixed call gates to NULL segment to throw #GP(0) correctly.

With the latest improvements, Windows NT now generates a STOP 0000007B inaccessabls boot device? Anyone?

Edit: Interestingly, I see no non-#PF faults anymore. Only lots of page faults(only whatt seems to be stuff like copying memory blocks usimg MOVSD mostly between 000XXXXX and 800XXXXX)? Anyone knows more about this?

NT 3.1 BSOD


Anyone can tell me more? Apparently the kernel crashed?

Edit: I added a simple log (temporariiy), logging all page faults.
Code: Select all
   dolog("pagefaults","#PF on instruction 0F:%u OP:%02X R/M:%02X at %08X on VA %08X code %04X",CPU[activeCPU].lastopcode0F,CPU[activeCPU].lastopcode,CPU[activeCPU].lastmodrm,CPU[activeCPU].registers->EIP,address,flags);


This resulted in the following log:

Anyone can see something that isn't supposed to happen?
Edit: Added ModR/M byte to the log.

Re: UniPCemu Windows 95/NT progress and issues

Postby superfury » 2019-2-26 @ 00:46

With the latest bugfixes, I now immediately see it #PF on LA 0 using DS(23h):0 as a pointer after the #UD(using opcode 01h, ADD), which NT doesn't like...

Still typical, fixing one bug, another one pops up(until none are left)!

It happens at 0008:80168E00, opcodes 011A(ADD DWORD [EDX],EBX).

I can trace the invalid return address which tries to use EDX as a pointer(RETF) to:

So the origin is at 8003540C?

Edit: So the cause is at 0003540C?

I then arrive at:

That writes 0x08000000 there? Then why is that weird value when it crashes there?

Edit: Hmmmm... REP MOVSD seems to be the cause:

Re: UniPCemu Windows 95/NT progress and issues

So Windows NT is trying to RETF to the location in the second DWORD stored in IDT vector 1(single-step interrupt)! That's already setup at the start of the log, which is even weirder!

So the code is using the IDT as something that's supposed to be an instruction or data address' location, and ret-ing to that location incorrectly? I smell a stack problem somehow... (probably some non-stack related error?)

Edit> Hmmmm... Interesting: searching upwards for the invalid EBX load(pointing to the IDT), I find:

That's byte 0x38 of the TIB it's loading 0x80035400(The IDTR) from?

Edit: According to http://nasutechtips.blogspot.com/2011/0 ... nd-fs.html , that's supposed to be 'last status number'?

Edit: Interestingly, immediately after updating an IDT entry at IDT+0x30(The #UD handler), it executes an 80486 0FA6 and #UD faults.
Edit: It then gets to 801bae33, which it just set up.Then a #UD, which is handled and returning, then some more IDT set-up and then faults on the ds:[edx] dereference.
But before setting up the #UD fault handler, it clears EAX and moves it to EDX. That EDX value is used at the end, page faulting on it?

Re: UniPCemu Windows 95/NT progress and issues

Interestingly enough, I see only one fault being raised by the CPU before triggering the NULL pointer dereference which causes the BSOD: an INT1 exception is being triggered? That doesn't seem to be supposed to happen?

Edit: It seems to happen because the trap flag is set? The last instruction was a POPF instruction(which seemed to have set said flag).

Edit: So the primary problem in this case is that the trap flag is set when it shouldn't be?
Edit: The OS loader displays 10 dots, then becomes smaller(due to the 50 row height taking effect)...

If I remember correctly (was a while ago), NT3.5, possibly 3.1 required the single step exception to boot, so this is probably intended. I don't think NT4 did.

Well, it seems to cause a page fault(null pointer dereference) directly after doing some IDT modifications(80486 CMPXCHG faulting on the 80386 emulation), then setting some more vectors, then setting the Trap flag(by means of an POPF instruction), whose handler(the Trap fault handler) page faults(LA 00000000, cause [EDX], which is cleared when restoring the IDT #UD vector), which executes INT3, which displays the NT BSOD(and waits for some debugger to connect to the modem on COM2).

An improved log(with exception 0-8 properly added):
https://www.dropbox.com/s/u5kwrma71o40r ... 40.7z?dl=0

Hmmmm.... I see the exception handler at 801bae82, but disassembly doesn't match what's read from memory(during the exception)?

Whoops! That's because the interrupt is incorrectly being handled!

The interrrupt pushes it's data on the stack and jumps to the interrupt handler(the EFLAGS,CS,EIP being pushed).

But once it's starting the first instruction from said handler(initializing instruction phase), the REP bugfix (that's there to reset EIP while repeating for correct behaviour during faults) resets CS:EIP back to the interrupted instruction(without updating the CS descriptor cache and TLB) flushing the PIQ, executing with kernel CS and (user) selector the (user mode) REP instruction again(if paged at least... imagine.... :S ).

Edit: Having fixed that, it's back to to 0x7B inaccessable boot device(only page faults).

This is what BSOD I'm getting now:

Windows NT BSOD after fixing REP faults.


Edit: Slightly improved the logging of the Page Faults:
Code: Select all

Re: UniPCemu Windows 95/NT progress and issues

Postby superfury » 2019-3-01 @ 17:04

Just tried Windows NT 4.0 Workstation, which crashes with the same error message:

1058-Windows NT 4.0 disk 2 BSOD.jpg
Disk 2 of the floppy boot gives a BSOD.


Interestingly in all cases, I see that some SCSI driver is loaded, but no required ATAPI(for CD-ROM) or ATA(for the HDD) driver is loaded?

I do remember getting the INACCESSIBLE_BOOT_DEVICE error at one point, but tried going back in my commit history and couldn't really find a build where it stopped with that error on NT3.5. The NT4 issue was in the ATA controller interrupt timing/behavior.

So, how accurate does the timing need to be? Do I need to implement all the ATA-1 timings exactly, or only adjust the interrupt timings?

Edit: It now has:
- 300ms until reset complete.
- 670ns until raising IRQ(after finishing a command).
- 50us for a drive select.

All other timings are 0ns(no delay).
