Sample example not working: fileio.exe

[Joel Sherrill]

Thomas,

It is probably just a setup issue on my side but the IDE
driver locks up during initialization on qemu before Init
runs.

Program received signal SIGINT, Interrupt.
ata_process_request_on_init_phase (ctrl_minor=0, areq=0x15da10)
at ../../../../../current/c/src/libchip/ide/ata.c:1422
1422 (!(byte & IDE_REGISTER_STATUS_DRDY)));
(gdb) bt

../../../../../../../../current/c/src/lib/libbsp/i386/pc386/start/start.S:184
#6 0x00000000 in ?? ()

Stepping into the check, I see this:

(gdb) s
102 uint32_t port = IDE_Controller_Table[minor].port1;
(gdb) s
105 if (reg == IDE_REGISTER_DATA_WORD) {
(gdb) s
111 inport_byte(port+reg, bval1);
(gdb) p port
$1 = 496
(gdb) p reg
$2 = 7
(gdb) p/x port
$3 = 0x1f0

So it is hanging on the first IDE interface's status.

My qemu invocation is:

qemu -M isapc -m 8 -boot a -fda /home/joel/qemu/pc386_fda \
-hda fat:/home/joel/qemu/hd -serial stdio -s

I don't know if this is THE problem here or not but it is
stopping for me. :)
