Subject: CDROM: allow to boot from MacOS 7.6 CDROM
X-Git-Tag: v4.05.00~3
X-Git-Url: http://git.codesrc.com/gitweb.cgi?a=commitdiff_plain;h=0c1e0071de622b9b68ef9dd65978db6ca67240a3;p=SCSI2SD.git

CDROM: allow to boot from MacOS 7.6 CDROM

Reading one sector from the CDROM is always reading several (4)
from the SD card, so always set multBlock to one in this case.
