Let me give some examples... The ISO9660 driver for Linux

Hello Eric,
Depends. If you want to be able to BOOT from ext4, you would
have to boot a virtual MEMDISK boot floppy from GRUB, then
load your new driver to open the ext4 partition ;-)
That sounds a lot like using an initramfs in Linux. Am I getting the
right idea?

You would probably write it as a protected mode TSR using the
network redirector interface, similar to VMSMOUNT for FreeDOS.

Hello everyone,
Suppose I wanted to write an ext4 driver for FreeDOS and integrate it
such that it's possible to use ext4 on a system partition. And let's say
this plan materialized - would this have any effect on existing DOS
software? I'll go on why do I even consider this, but I want to kno
Hello Eric,
I would be very pleased to conduct tests that aren't just about
permanent storage IO. I'm also curious how does FreeDOS perform.
I have such a platform:
- Abit VP6
- 2x Pentium 3 @ 1.4GHz (Tualatin, SMP compatible, require Lin-Lin
sockets, usually running at 700MHz)
- 128MB SDRAM

Jack is indeed one pronounced critic of our I/O speed.

You could try using lbacache with the flop option and
tickle for FreeDOS and/or DR-DOS, and compare with a
DR-DOS cache of your choice. Check whether the caches
correctly notice disk c
Hi Eric,
I have Pentium 133 Mhz with normal IDE drive a then bunch of laptops with 386,

They run different brands of DOS operating system. FreeDOS is of course
installed as well ;-) But problem to run same test on same hardware but with
different OS.
