There is a tool, but block devices won't chain in under dosbox.

Well, another solution is to setup a ramdrive outside of dosbox and just mount it as a drive.

Right, though hd speed and even external drive speed is usually no issue
especially when the drive/device is read-cached/read-ahead.

and have fun with the maximum size of 63mb for the ram drive......unless you can find a ramdrive program that uses HD space as swap. 😁

One of the guys from the closed thread was saying he was having issues with his flash drive, so perhaps this would help. Any rate, there is an available solution.

If you're referring to a 63MB limit in dosbox, that's only a compile correction away.

Flash drives are fast to read (access time is 10 times lower than average hdd) but slow to write. If running from flash is slow, the game must be writing to it...which is very bad for flash 😜 Although at current prices, even if you change it every month... 😀

that's only a compile correction away.

There's more to it (xms interface), but it's irrelevant at that point.

Ya, I was only addressing the memory limit. I take it block device handling needs some linked list or other to chain? That's my best guess from your comment:), but I don't know the details of the handling.

There's way more about it. The chaining in a linked list (device chain) is needed
for char devices as well, but block devices additionally have drive letters assigned
to them, and a fullblown access interface (i don't know too much about it as i've
never dealt with it).
