Shouldn't be that long. It depends on what it's trying to do, maybe lots of seeks and temporary files?? Does it use EMS or similar? > I haven't done it in DOS in a very long time, as I do my email with SeaMonkey > in OS/2. > > When I tried DOSbox and DOSemu, I simply noted that the waits seemed similar > to those in PC DOS, without doing any measuring. DOSBox doesn't count, nothing is supposed to be fast (or even totally accurate) there, it's only for games. And even though I think DOSEMU is better (and faster), it's still rough in some areas. Same with VirtualBox, still lags and has bugs, not representative of real hardware (though 30 years of legacy is a lot of variance in speeds!!). > All of this is on non-antique hardware, with ATA100+ or SATA HDs and CPUs > running upwards of 1.6GHz.

Newer machines don't play as nicely, and sometimes 16-bit is explicitly slower than others due to design decisions. Though if you're not running UIDE (or at least LBAcache), you've only got yourself to blame. ;-) > I haven't spent much time with FreeDOS because it's installation process is > so un-DOS-like, meaning there's no downloadable media I've found that lets me > make a floppy and do SYS C:, quickly XCOPY what little I actually need into > C:\DOS, and boot it, instead making me boot a CD and navigate through menus > full of stuff I know little and care nothing about. Floppies aren't really made and sold very much anymore, and they've been dropped by most hardware companies. There's very little interest in them. But if you insist on (slightly older) floppy images, try here: http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/unofficial/odin/odin060/ Or my wimpy one-disk version from 2008: https://sites.google.com/site/rugxulo/BARE_DOS.ZIP?attredirects=0 And once you've got the older version installed, you can install the newer kernel and tools (either manually or mount the .ISO on your HD via SHSUCDHD). ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
