Thanks for the link! Here is a version which works in Linux:


#include <unistd.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <stdio.h>

#define st 34
#define sz 92

void cnvt (int n, unsigned char *b1, unsigned char *b2)
{
  unsigned int i, j, l, b;
  unsigned long x1, x2;
  unsigned char k[4];
  j = n * 52;
  for (i = 0; i < j; i++)
    b1[i] = 0;
  n <<= 4;
  for (b = i = j = 0; i < n; i++, b += 26)
    {
      x1 = b2[j + 3] - st;
      x2 = b2[j + 2] - st;
      x1 = (x1 * sz) + x2;
      x2 = b2[j + 1] - st;
      x1 = (x1 * sz) + x2;
      x2 = b2[j] - st;
      x1 = (x1 * sz) + x2;
      j += 4;
      l = b & 7;
      x1 = (x1 << 6) >> l;
      k[3] = b1[b >> 3];
      k[2] = b1[(b >> 3) + 1];
      k[1] = b1[(b >> 3) + 2];
      k[0] = b1[(b >> 3) + 3];
      *(long *) (&k) |= x1;
      b1[b >> 3] = k[3];
      b1[(b >> 3) + 1] = k[2];
      b1[(b >> 3) + 2] = k[1];
      b1[(b >> 3) + 3] = k[0];
      if ((i & 15) == 15)
        j += 2;
    }
}


int main (int c, char **v)
{
  unsigned long x, y, z;
  int f1, f2, i, j, k, l;
  unsigned char b1[13 * 512], b2[(16 * 512) + 256];
  if (c < 3)
    {
      printf ("REPACKER Source Dest\n");
      return (20);
    }
  f1 = open (v[1], 0);
  if (f1 < 0)
    {
      printf ("Cannot Open Source\n");
      return (20);
    }
  f2 = creat (v[2], 0);
  if (f2 < 0)
    {
      printf ("Cannot Create Dest\n");
      return (20);
    }
lp:
  i = read (f1, b2, (16 * 512) + 256);
  if (i == 0)
    return (0);
  j = i / 66;
  l = 0;
  if (b2[(j * 66) - 2] - 13)
    {
      l = b2[(j * 66) - 2] - st;
      l -= 52;
    }
  cnvt (j, b1, b2);
  k = (j * 52) + l;
  if (write (f2, b1, k) - k)
    goto werr;
  if (l == 0)
    goto lp;
  return (0);
werr:
  printf ("Write Error\n");
  return (20);
}

(I have inserted "thatcharacter" instead of the at sign into the last line of the license text to keep the BTTR forum from making the email clickable and spammable)

However, remember that the rloewelectronics.com website says:


WELCOME
To the memorial homepage of
R. Loew Electronics Consulting
Rudolph Loew (Rudy) passed away on September 11th, 2019.
This site is maintained by his family to archive his work and make it available to anyone who is interested in pursuing further endeavors. You can view the original un-modified site here. Please do not try to make any purchases, all of Rudy's projects will be made available (including source code) as time permits.


The driver can also be downloaded on:

https://rloewelectronics.com/distribute/AHCICD/1.1/

It should be feasible to get some confirmation that the license no longer applies and include that in a package which can be distributed for example as part of a FreeDOS distro. Would be nice to have an open source AHCI driver with a free open source license. Maybe MIT or BSD? The disclaimer on the website sounds a bit like "public domain" but it would be nice to still remember the original author.
