How do I properly read multiple sectors from a disk using 28-bit PIO in assembly?

How do I properly read multiple sectors from a disk using 28-bit PIO in assembly?

This is my load sectors subroutine:

load32:
    jmp load32_skipvars:
    load32_source dd 0
    load32_return dd 0
load32_skipvars:
    mov dword [load32_source], esi
    mov dword [load32_return], ebx
    mov ebx, ecx
    mov al, byte [load32_source + 3]
    or al, 0xe0
    mov dx, 0x1f6
    out dx, al
    mov dx, 0x1f1
    mov al, 0x00
    out dx, al
    mov dx, 0x1f2
    mov al, cl
    out dx, al
    mov al, byte [load32_source]
    mov dx, 0x1f3
    out dx, al
    mov al, byte [load32_source + 1]
    mov dx, 0x1f4
    out dx, al
    mov al, byte [load32_source + 2]
    mov dx, 0x1f5
    out dx, al
    mov dx, 0x1f7
    mov al, 0x20
    out dx, al
waitforit:
    in      al, dx
    test    al, 0x08
    jz      waitforit
    mov     ecx, 0x00000100
    mov     edx, 0x000001f0
    rep     insw
    dec     ebx
    cmp     ebx, 0
    jg      waitforit
    jmp     [load32_return]

Which can be called like so:

    mov esi, dword [kernel_cluster_loc]
    mov edi, dword [kernel_put]
    xor ecx, ecx
    mov cl, [bpb_sectors_per_cluster]
    mov ebx, morekernel
    jmp load32
morekernel:

This loads the multiple sectors as it should, however, there are multiple sectors of "FFFFFFFF" between them, breaking it into pieces so it's not contiguous.

This is what the memory looks like after loading:

Offset(h) 00       04       08       0C

The three parts that aren't "FF" are the whole file, I just cant figure out how to get it loaded properly. I assume this has to do with the waiting needed between sectors, but I have it go back after each sector to waitforit what am I doing wrong?

You forgot to restore dx to 1f7h (The ATA Controller Status Register) at the end of the loop.

Failing at restoring dx will make the test for bit 3 (DRQ) to happen on the Data Register.
Since, due to electrical legacy, an unserviced IO read returns a datum with all the bits set, the test always passes leading you to the offending reads.

It's a bit curious how the controller returns the correct data only after an integral amount of sectors (512 bytes) has been read - probably due to some internal counter/latching logic.

This is a bit off-topic but if I may, let me give you one more advice.

Robustness

1. Always check if the controller is ready to accept a new command (bit 7, BSY, of the Status Register).
2. Always check if the last command succeeded (bit 0, ERR, of the Status Register) along with the Error Register.
3. Check if the controller and channel selected have an attached and ready device (Bit 6, DRDY, of the Status Register)
4. Establish a calling convention, particularly which registers should be preserved, or adhere to an existing one (if you are going to use, e.g., C).

Readability

1. Use the stack to save your local variables, not global vars.
2. Use calls/returns not jumps unless you have a specific reason not to.
3. Don't put variables in the flow of execution, place them between functions if you don't have a data segment.

The "programming reference" for old AT controllers or PCI attached ATA controllers is the ATA/ATAPI 6 specification which is basically one of the latest before the introduction of SATA.
It also describes the ATAPI (e.g. advanced disk management, CD-ROM readers) interface and all the possible defined commands.
It is surprisingly comfortable to read, just be warned that you won't find IO ports addresses but offsets (encoded as asserted/non-asserted pins but that is just the binary pattern of the low bits of the port address).
