You can get a 1G Compact Flash Drive for less than $50.

It would depends on the IDE-CF adapter. Our cheap adapter works fine
on a 486, even for a 2G CF.

It is a CF feature enabled by the adapter. Yes, you need it by
default.

I know, I was talking about a DOC chip. I know a CF is quite cheaper.

Which is your CF adapter? Maybe I need one of those...

So, I need the feature both in the CF and in the adapter?

Is there any way to modify my CF-IDE adapter to enable True-Ide mode?
Some level at some pin...?

Thanks!

The ATA mode pin must be grounded to enable it. This is usually not
the problem. However, some adapters are wiring other pins
incorrectly, which is a pain in the neck to correct. That's why we
developed our boards.

I have one by one checked every wire in my CF-IDE adapter, and it seems
to comply with the true-ide mode. I used this table as a reference:

http://www.compuphase.com/mbr_fat.htm#CF_IDE

So I assume that if my adapter is attending to this table directions,
and as I am able to use the CF+Adapter on a Pentium IV, I am not having
a compatibility mode issue.


How can I make it work on a 486??? I think Linux doesn't obbey to BIOS
configuration for disk drives. Anyhow tried with "auto" and with "user
->977/8/32" setting. Nothing changed.

Please, give me some ide to check... My last step in this project is
moving all the filesystem to a compact flash, and I have found a big
obstacle here..

Thanks!

You might have better luck using our Embedded Slackware on a CF.
Slackware is an i486 distro. The SDK is available for i486,
uclibc_i486, pxa25x and uclibc_pxa25x. The makeCF utility
allows you to select components etc. and creates the base
bootstrapped CF automatically. You will need the 3 (12MB, 10MB
and 13MB) archives:

slakbootEBS-base+i486a
slakbootEBS-i486b
slakbootEBS-i486c

Hello,

> Cyrix 486 DX4-100 MHz processor.

I am using a CF2IDE adaptor on a Cyrix 486 SLC/40 based system. But it's no
special board, I got it from my aunt's old pc. It works perfectly.

> So I decided to use a cheap Compact Flash card. I bought an IDE-CF

I didn't use it on my main system, but on the 486 I didn't need anything.
I am using a 32 Mb CF from my photo camera and I also bought a 64 Mb chip
for it. The third (the cameras original 8 Mb Chip) works also very well. I
set up the BIOS for "AUTO" and it recognized it without any problems, then I
ran fdisk on the chip (booting via loadlin on the very same system - 2.2
kernel + busybox) and filled in the settings into the system.

I ran also DOS for a while, but it couldn't satisfy me.

You could try to put the CF adaptor as hda. Is it jumpered correctly?

Are you sure the CF works flawlessly in a camera or a card reader?
Did you try another (maybe smaller) CF?

You shouldn't have to use a append line.

The same version worked for me also. Right now I am running a 2.6 but it
takes too much memory (I've got only 8 Mb).
You should - if not needed otherwise - only include the IDE support. CF2IDE
makes the system think it is using a true (spinning) IDE disk, not as a
flash chip. Maybe you just have to kick out some things.

Strange.

I don't know anything about it; I just put my in and bootet. And it
worked...
The system and so on were put on the CF by using a simple (internal) usb
card reader.

I found out that with only one CF inserted (I've got also a dual adaptor
with both hda and hdb as CF disks) I don't need any power supply for it. The
TTL levels are enough to power the CF :-)

Hope this helps,
Sebastian

You're lucky !! :-)

> You could try to put the CF adaptor as hda. Is it jumpered correctly?

The are two jumpers. First selects master/slave. It works. Second, I
was told that was for select the source of power, between +5v and +12v,
both from a floppy connector. As I have both 5 and 12 applied to the
floppy conector to the CF-IDE adapter, tried to change the jumper and
nothing happened. Anyhow, I cannot configure it as a master, because it
has no operating system yet, so when trying to boot from it, it will
fail and I won't be able to check if Linux sees it.

> Are you sure the CF works flawlessly in a camera or a card reader?

Yes, I have checked both the adapter and the 128 Mb CF in my Pentium IV
and it works great.

> Did you try another (maybe smaller) CF?

Yes, I also tried a 8 and 32 Mb CF in the adapter. Both work OK in my
Pentium but neven on my 486's

I compiled with IDE and aaaaaaaaaall the modules which might have any
relation with memories, flash, mtd, rom.... everything...!

I hope I can reach that stage sometime...! :-)

Bueno, you could. But, you would have to replace the structured
component directories, which contain the burn files, with RH
versions, where applicable. Particularly you would have to
change the contents of slaketcs/i486 with Redhat's boot (init.d)
components. The bootstrap is also set to use lilo, which might
be a problem...

But i'm not sure this is what I need.. Does it have any specifil kernel
module? I don't need any particular application to manage the flash,
this is not a problem yes. My problem is that my kernel does not see
the compact flash. At the moment I can see it, I will dump the FS to it
and go on...

I don't think so, because I am really tight on memory (normal 30pin-SIMMs 1
Mb each ... 8x1 = 8 and more isn't possible. I never saw any simms with more
than 1 Mb and I doubt it would be recognized.)

My adaptor has only one jumper (the single CF one). I would try to jumper it
as master and boot the kernel from a floppy disk (simple zimage will do), if
that's possible with your board.
Otherwise you could fill the CF with a operating system using DOS or
Syslinux. Then you could directly boot from it and maybe you'd see the
error. My adaptor doesn't work as good if I jumper it as slave. Sometimes it
doesn't recognize the card, but I would have to check again to be sure. I
don't need it - I don't try it :-)

Maybe - I doubt it, but worth a try - all the modules disturb each other.
You could try to create a kernel as small as possible. No module support, no
flash support, nothing except floppy and IDE hard disk support.

My other problem is linux, as I can't get it to work as I want to.
My only requirements are:
=> kernel, busybox, nfs server
=> serial console (now I have a graphics adaptor which I want to remove)

But I can't get it to work... no idea how shared libs and so on work.
Nothing worked yet.
Only static builds and simply copying the host libs (thank god they're
386-compiled *g*)

Hope this helps,
Sebastian

My "server" i486/33 has 4*4 + 4+1 = 20 MB of 30pin-SIMMs.
It's 11 years 365*24h on line

Does your kernel has support for USB devices?
If you can access usb devices, you should be
able to map a CF mounted on a USB card reader
with the loop device..

There is a program at my web site (see way below
for URL) called burnit. You can use it to create
or extract a filesystem from a CF, but if you run
'burnit -l', it will just query for the first USB
card reader mounted, that it can find. It might
also display some messages, to show what is missing
in your system ...

Fall is my favorite season in Los Angeles, watching the birds
change color and fall from the trees.

Nice, then. I never found such memory, unfortunately. So I'm stuck.

It is not a kernel issue. The kernel I compiled for the 486, booted in
my pentium IV, is able to see the CF correctly.
My CF adapter is via IDE port, not USB port.

If my kernel lacked some module, it would not work on my Pentium IV...

Regards!
Eduardo
