Subject: at_wini: bump hardcoded ATAPI limit to DVD size
X-Git-Url: http://zhaoyanbai.com/repos/%22http:/www.isc.org/icons/Bv9ARM.ch02.html?a=commitdiff_plain;h=refs%2Fchanges%2F01%2F3501%2F1;p=minix.git

at_wini: bump hardcoded ATAPI limit to DVD size

at_wini was previously hardcoded to present ATAPI devices as having a
size of 800 MiB, which was enough for CDs but not for DVDs.  This
patch increases the device size to 8500 MiB, which should be large
enough to cover all DVDs.
