[t13] DRQ not being set

[Fuster]

This message is from the T13 list server.


Hi,
   Why isn't the DRQ is not being set to 1 ? 
 If there is some error in the below code please do mention how to
correct it . The functions printf,inb,outb are working.

Any other corrections to be made to just read the 1st or 2nd byte ?

Here is code.

static inline void insw(unsigned short port, unsigned char *addr,
                        unsigned long count)
{
        __asm__ __volatile__("rep; ins" "w":"=D"(addr),
                             "=c"(count):"d"(port), "0"(addr),
"1"(count));}

void hd_init(void)
{
        unsigned char *p, c[512], *e;
        e = c;
        while ((inb(0x1f7) & 0x80) == 0x80) ;
        printf("HERE 1\n");
        outb(0x1f2, 0x04);
        outb(0x1f3, 0x07);
        outb(0x1f4, 0xa7);
        outb(0x1f5, 0x00);
        outb(0x1f6, 0xa3);
        outb(0x1f7, 0x20);

        printf("%x", inb(0x1f7));
        /* Prints 0x50 . So the below loops forever.
         */
        while ((inb(0x1f7) & 0x80) == 0x80
               || (inb(0x1f7) & 0x08) != 0x08) ;
        /* Doesn't break out of this loop. Something wrong here. 
         * But as per the hardware spec this is what is expected.
         * Corrections to be made in this loop.
         */
        printf("HERE 2\n");
        insw(0x1f0, e, 256);

        printf("%x %x #####\n", c[0], e[0]);
}
