I cannot load the ACPI module in 5.0-current and get a working floppy drive
simultaneously. With ACPI loaded the dmesg | grep fdc0 is:
fdc0: cmd 3 failed at out byte 1 of 3
fdc0: cmd 3 failed at out byte 1 of 3
fdc0: cannot reserve I/O port range (6 ports)
With the ACPI module disabled in /boot/loader.conf, I get:
fdc0: <Enhanced floppy controller (i82077, NE72065 or clone)> at port
0x3f7,0x3f0-0x3f5 irq 6 drq 2 on isa0
fdc0: FIFO enabled, 8 bytes threshold
fd0: <1440-KB 3.5" drive> on fdc0 drive 0
I have the latest BIOS firmware, and I've been told by my M/B vendor's support
organization: "ASRock motherboards are all ACPI complaint" and "All our
Produsts are fully support and fully tested with Windows 98SE/ME/2000/XP. We
won't provide any support to Linux or other OS like FreeBSD."
I replied to ask them "why not?", however what can the issue be where they
claim compliance on all versions of Windows yet FreeBSD doesn't work? Is
this a case where Windows has it's own "standard" that no one else meets, or
is FreeBSD support still incomplete?
I not sure if this is relevant, but here's a chunk of acpidump output related
to the device FDC0:
Device(FDC0) {
Name(_HID, 0x0007d041)
Method(_STA) {
If(FDST) {
Return(GSTA(LDFD))
}
Return(0x0)
}
Method(_DIS) {
DDIS(LDFD)
}
Method(_CRS) {
Return(FCRS)
}
Method(_PRS) {
Return(FPRS)
}
Method(_SRS, 1) {
DENB(LDFD)
}
}
Thanks,
