changing root device to wd1s1a
Intel Pentium F00F detected, installing workaround
>Description:
I created a 2.2.6 boot floppy from the 2.2.6 install CD. It
booted successfully and I adjusted matcd0 to be found at port 0x340 in
user config, finished booting, and matcd0 was found. I set the media
type to CD-ROM, selected the Novice install, dedicated all of wd1
except a boot manager area to FreeBSD, partitioned wd1s1, and started
the install. The install procedure created filesystems and copied
/stand from the boot floppy to the new root partition. When
sysinstall tried to mount the CD-ROM, it appeared to try to mount
/dev/matcd0c on /dist. I got an error box saying:
Error mounting /dev/matcd0c on /dist: Input/output error (5)
I switched to the debug screen using ALT-F2 and found this message 7
times over:
matcd0: Illegal data mode for this track while reading block 64
After bringing 2.2.1 up with a 2.2.1 boot floppy that found matcd0 (!)
I mounted the CVS repository disk and took a look at what might have
changed between 2.2.1 and 2.2.6 w.r.t. sysinstall. Well, in 2.2.1
sysinstall's devices.c had an array device_names[], which I excerpt
here:
static struct {
DeviceType type;
char *name;
char *description;
} device_names[] = {
{ DEVICE_TYPE_CDROM, "cd0a", "SCSI CDROM drive" },
{ DEVICE_TYPE_CDROM, "mcd0a", "Mitsumi (old model) CDROM drive" },
{ DEVICE_TYPE_CDROM, "scd0a", "Sony CDROM drive - CDU31/33A type", },
{ DEVICE_TYPE_CDROM, "matcd0a", "Matsushita CDROM ('sound blaster' type)" },
.
.
.
{ NULL },
};
So in 2.2.1 we were mounting /dev/matcd0a. In 2.2.6, devices.c has
the same array, but it's changed quite a bit. Here's the appropriate
excerpt again:
static struct _devname {
DeviceType type;
char *name;
char *description;
int major, minor, delta, max;
char dev_type;
} device_names[] = {
{ DEVICE_TYPE_CDROM, "cd%dc", "SCSI CDROM drive", 6, 2, 8, 4, 'b' },
{ DEVICE_TYPE_CDROM, "mcd%dc", "Mitsumi (old model) CDROM drive", 7, 2, 8, 4, 'b' },
{ DEVICE_TYPE_CDROM, "scd%dc", "Sony CDROM drive - CDU31/33A type", 16, 2, 8, 4, 'b' },
{ DEVICE_TYPE_CDROM, "matcd%dc", "Matsushita CDROM ('sound blaster' type)", 17, 2, 8, 4, 'b' },
.
.
.
{ 0 },
};
So in 2.2.6 we're trying to mount /dev/matcd0c and it fails.
I note from the 2.2.6 matcd(4) man page the following:
SUPPORTED OPERATIONS
The matcd driver supports block and character access. Partition "a" re-
turns 2048-byte User Data blocks from data CDs. Partition "c" returns
the full 2352-byte Frames from any type of CD, including audio CDs.
(Partition "c" cannot be "mounted" with cd9660 or other filesystem emula-
tors.) No other partitions are supported.
So we should really be mounting /dev/matcd0a, not /dev/matcd0c!
>How-To-Repeat:
Try to use the 2.2.6 boot floppy to mount from CD-ROM on
matcd0.
>Fix:
I suggest changing this line
{ DEVICE_TYPE_CDROM, "matcd%dc", "Matsushita CDROM ('sound blaster' type)", 17, 2, 8, 4, 'b' },
to
{ DEVICE_TYPE_CDROM, "matcd%da", "Matsushita CDROM ('sound blaster' type)", 17, 0, 8, 4, 'b' },
I built a new boot floppy using this and it worked!
