When trying to use doscmd on 8-stable, all I get is: Error mapping HMA, HMA disabled: : Invalid argument Segmentation fault (core dumped)
The segfault happens at the end of mem_init(), when the allocated DOS memory (which is located at virtual address 0) is attempted to be written to. Apparently, the mmap() failure that causes the "HMA disabled" message is actually a fatal error rather than a benign one the could be ignored, as it results in no valid DOS memory allocation at all. Right now, the only older system I could test it against uses FreeBSD 5.x, where the mmap() works as expected. So does anyone have an idea why this mmap() call: if (mmap((caddr_t)0x000000, 0x100000, PROT_EXEC | PROT_READ | PROT_WRITE, MAP_ANON | MAP_FIXED | MAP_SHARED, -1, 0) == MAP_FAILED) { perror("Error mapping HMA, HMA disabled: "); HMA_a20 = -1; close(HMA_fd_off); close(HMA_fd_on); return; } yields an EINVAL now under 8-stable? -- cheers, J"org .-.-. --... ...-- -.. .
