   6 .TH SDCARD 7D "Feb 28, 2008"
   7 .SH NAME
   8 sdcard \- SD/MMC memory card driver
   9 .SH DESCRIPTION
  10 .sp
  11 .LP
  12 The \fBsdcard\fR memory card driver supports MultiMediaCard (MMC), Secure
  13 Digital (SD), and Secure Digital High Capacity (SDHC) memory cards. It uses the
  14 \fBblk2scsa\fR(7D) service to present these cards to the system as SCSI disks
  15 on a virtual SCSI bus, creating a child device to be serviced with
  16 \fBsd\fR(7D). Each card appears as its own SCSI LUN. Cards are hot-pluggable
  17 and removable.
  18 .SH DEVICE SPECIAL FILES
  19 .sp
  20 .LP
  21 Disk block special file names are located in \fB/dev/dsk\fR. Raw file names are
  22 located in \fB/dev/rdsk\fR.  See \fBsd\fR(7D).

  30 See \fBsd\fR(7D) and \fBblk2scsa\fR(7D). Additionally, \fBsdcard\fR may issue
  31 the following warnings, which indicate a failure to identify the card as a
  32 supported type:

  46 Device special files for the storage device are created in the same way as
  47 those for a SCSI disk. See \fBsd\fR(7D) for more information.
