Solved Dos driver for GT32N DVD.rw

Acer 5349 can boot via DVD RW Drive GT32N: Where to get its Dos driver, tho.:) Regularly under ms-dos, I can reached any other CD/DVD devices via below - ASPI2DOS.SYS ASPI4DOS.SYS ASPI8DOS.SYS ASPI8U2.SYS ASPICD.SYS BTCDROM.SYS BTDOSM.SYS OAKCDROM.SYS ASPICD.SYS TRICD.SYS VIDE-CDD.SYS But even tried popular(*) UIDE.SYS, gcdrom.sys & cdfs.sys, cdrom.sys(which fetched from the OEM built-in win7.OS), I still fail to access DVD RW Drive (GT32N) under ms-dos boot. * Screen shows what's the problem -- H:\>devload uide.sys /d:udvd1 /s80 DEVLOAD v3.21 - load DOS device drivers - license GNU General Public License 2 (c) 1992-2008 David Woodhouse dwmw2@infradead.org Eric Auer eric@coli.uni-sb.de Loading: H:\UIDE.SYS UIDE, 10-15-2012. 80-MB Cache, CD/DVD name is UDVD1.
