Windows NT 3.1/4.0 STOP 0x0000007B?

Emulation of old PCs, PC hardware, or PC peripherals.

Just found out something strange booting the Bochs' openBSD floppy disk. It executes a ATAPI reset command, then a ATAPI IDENTIFY, then a ATAPI PACKET command, sends one word, then says "wdc1:0:0: device timeout, c_bcount=0, c_skip=0"?

Edit: It seems to be executing the instruction F2666F, which is a REPNZ OUTSW? But the REPNZ is invalidated, thus not active? What should happen in this case?

Edit: Just changed the REPNZ instruction to actually act as a normal REP for INS and OUTS instructions, instead of invalidating the REPNZ prefix altogether. That should fix that bug.

Thinking about it, that 8 sectors.... That's exactly 4KB? Perhaps that has something to do with the issue?

Perhaps something to do with paging or something to do with it?

Hmmm... The final INSW was a word from the 8th hard disk sector(loading sector 0x48 as the next sector, becoming busy for 60000ns('reading the next sector from disk', with an IRQ following that delay to start reading the next sector from the disk controller)). It has 0x37 sectors(started out with 0x3F sectors) left to read from the disk. The next sector is supposed to be read at logical memory location 0x

At that point, I see no more disk access(except the status register), no page fault of any kind.

After that, I see it being busy for some time, then the status register becomes 0x90(when it raises the IRQ)?

It seems like it's resetting the device before the IRQ arrives? That 0x90 is actually Windows NT having reset the device.

Edit: Hmmm.... With earlier sectors, it reads the status register twice, reading 0x58. But the final one(when it resets after that), it reads it for a third time(also finding 0x58)?

Edit: Hmmm... I see the status register reads after a new sector arrives at EIP of 80407004. The REP INSW is at 80407042.

The status register reads are always at 0x80407004, including the strange third status register read after the sector where it resets the ATA controller?

Edit: This is what happens after the second status register being read:

Hmmm.... Looking through the log, I don't see the PUSH EBX instruction actually writing memory(immediately after the very first CALL instruction):

However, inspecting the instruction PUSH EBX itself, it seems that it DOES write correctly to memory, it just isn't logged somehow?

Re: Windows NT 3.1/4.0 STOP 0x0000007B?

Postby superfury » 2019-6-10 @ 16:36

Just tried NT4's setup again. I notice that the same issue happens there, but it's booting from a floppy disk, not a hard disk? It gives a STOP 0x0000007B (0xFF85CED0, 0x00000000, 0x00000000, 0x00000000)?
