No cache will ever compete with a RAM disk. RAM is always faster
than disks with their seek/rotational latencies and their much
slower transfer rates.
I knew this would provoke a comment from you, Jack.
The purpose of a cache is to put as much data in RAM as it can, so that the

I knew this would provoke a comment from you, Jack.
Yes, you always were a provoker, weren't you, Bret?
The purpose of a cache is to put as much data in RAM as it can, so that
the disk is accessed as little as possible. It's true that the cached
data does eventually get written to

Does this work for any size floppy image or only 1.44MB?

Hi Bertho, trying to reiterate / re-explain my plan /

Fine !
a DRIVER could interface with any disk with
any sector size and then just provide an int13 or int25/26 interface
with 512 byte sector size for data transfer to DOS.

Also, FWIW, you can disable write-delay caching in SMARTDRV if you want,
in which case it works sort of like UIDE or LBACACHE (except that it
will also _natively_ work with non-INT 13h disks like USB and SCSI), but
at the expense of requiring more memory.

SCSI disks are rarely seen on PCs, due to their high disk and controller
cost. USB disks are also rarely seen, since they are not-yet reliable,
nor in many cases are they fast-enough to replace hard disks. SATA/IDE
own the hard-disk market and probably

Thanks everyone for all the responses. I guess there is not a how-to for
creating a bootable FreeDOS CD? That is, it takes fiddling and
experimentation and a successful method has not been posted to the
FreeDOS wiki? The point of greatest interest is what files are needed on
the CD, exactly
Alain,
I would like to try your method. I did something like this a few months
ago but evidently missed a step since my CD would not really boot. This
was to enable flashing a BIOS update on a motherboard.
Can you tell me the names of all the files needed in your step 7?
Perhaps I missed a

I'm not opposed to this method, which I see as a workaround rather

Hi Jack,
Try to find any Write Back caches that do so much, for so little memory!
Sure, it takes more memory. If it is not just local pooling
within a few kB and with tiny timeout, it will take even more
memory, for logics and extra security logics for writeback.
But larger writes really

That's a *very* interesting link, thanks!.
Bedtime now though.
I wish DISKCOPY was able to handle different floppy image sizes
(360KB.IMG to 1.44MB floppy for example, or backup a (SHSURDRV?)
harddisk image uncompressed).
Hi Alain,
Thank you very much for this, I downloaded it. I'll play with it and see
if I can get this BIOS flashing to work.
It is clear that I need to develop technical knowledge of FreeDOS if I
want to learn how to flash some motherboards properly.
Again, many thanks!

It is a standard isolinux image.
Has anyone made that?
