I got an OSR2 recently and I install it on a ms-dos machine. It seems everything works fine. Until I try to boot to ms-dos by pressing PF4 when the system starting up. MS-DOS did start up, but when I restart it again, OSR2 cannot start again. It doesnt even prompt the "starting windows 95..." msg. I check and find the io.sys, msdos.sys doesnt switch properly.
So I guess if the the dual-boot support is changed in OSR2?
