Hi, all.
I've tried to install FreeBSD/pc98 7.0-BETA2 to PC-9821Xa9 via FTP.
Installation is finished sucessfully.
But cannot use the internal ATAPI CD-ROM drive.

The CD-ROM drive works well with 7.0-BETA1 and 6.3-BETA1.
To use the CD-ROM drive with 7.0-BETA2, I have to apply a quick patch
described below and recompile the kernel:

The value of cdp->cap.medium_type is 0 (MST_FMT_NONE).
