In addition to that, a Fujitsu IDE drive and a Micropolis drive both had write protect jumpers. Those would be hard to find as would the right mainboard, but it's worth checking your BIOS at least.

What i would like to have is a switch connected or whatever that lets me physically enable write protection on the fly and not only at boot, cause i want to be able to update my system without the need to reboot. I just don't know how to do this for now, but that's my personal goal. So the router is protected as long as the switch is on "write protection", if i change something i have to physically press a switch on this machine... Only achieving protection for the hd could be done using other methods, maybe, like looking for a way to let linux only mount it read only in the kernel or whatever (maybe use grsecurity massivly or LIDS).

A simple question: What if during the initial boot process you mount your hard disk as a read-only device then delete the mount command? Would this be sufficient protection for a HD? (i.e. Is there any other program that could be used to remount the HD?) Saving config changes could be handled by mounting a config floppy during the init process that never gets umounted during normal operation.

Hey! Someone might be interested in an assembly code software write-protect program for IDE devices that intercepts int13 calls (or something like that, I don't get it all) http://wcarchive.cdrom.com/pub/simtelnet/msdos/diskutil/protect.asm Download the file and read it.

Lynn, If I understand you correctly, you believe Apacer was telling Stefaan that Host Selectable (Close 2,3) mode wasn't supported, not that Connect to Ground (Close 1,2) didn't work. Since there is no WP jumper on the ADM, we need to create an adapter that jumpers pin 30 to ground when WP is desired. Did I get that right? Anyone willing to try this, and see if it works? If it's this easy, I can't understand why SST/Apacer didn't add a two pin WP jumper (Close 1,2) to the ADM. -- Mike Noyes <[EMAIL PROTECTED]> http://sourceforge.net/users/mhnoyes/ http://leaf.sourceforge.net/content.php?menu=1000&page_id=4 ___ Leaf-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-devel

OK, this is where I might be confused myself, and confusing others such as Matt. Let me explain it as I understand it, and everyone is welcome to thrash me into submission if wrong. As noted in the email and to a far lesser degree on the White paper, pin #30 _can_ be used with a special MB to control the WP, in particular with _partial_ software_named files/dirs to WP. The WP used with the pins #1-2 does not require the special MB or ATA instructions, simply a jumper or a jumper with switch, but you can't do partials. Now comes in my somewhat OT comments/thoughts of yesterday. Being that this jumper configuration does not require a special MB or ATA instructions beyond what is presently used, only a jumper that bypasses the disk itself (to ground) ... Is there any reason that this could not be implemented on any or all existing ATA run devices (CF, FlashDisk, IDE, etc), the jumper is bypassing the drive itself as far as the instructions on wire #1 is concerned The reason I bring this up at all is quite simple, I believe that the general population has old hardware that could be used for LEAF similar to mine roughly 30 old 486-P1 boxes that support IDE only (no SCSI support built in). The cost of a SCSI controller board is too expensive, or won't fit in the desired case restraints desired, so though it's a excellent option, it's not a desired option. I have flash and CF cards at present that I would like to use WP if possible through existing MB's ... a manual switch or even a $10-20 module would be more cost efficient and desired than simply trashing what I already have, hardware wise, to get WP, if possible. In other words, how many folks have said: "Can I run LEAF on a harddrive (IDE)". We say, "you can, but it is a security risk compared to a floppy". What would it mean to be able to say: "You can use a hd, but if you want it as secure as the floppy, a $10-20 add-in IDE module is available here (link)." I think a lot of people would find this useful, IMHO, or maybe I'm thinking too hard and flogging a dead dog! -- ~Lynn Avants aka Guitarlynn guitarlynn at users.sourceforge.net http://leaf.sourceforge.net If linux isn't the answer, you've probably got the wrong question! ___ Leaf-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-devel

Um...you won't find any standard motherboards that support the usage of pin 30 for write-protect, and even if you could, it would probably be controlled by software, not a switch, which kind of defeats the whole purpose. That's the entire reason the WP jumper is on the device in the first place...you can use the pin 30 interface if you're designing a custom board...folks with standard hardware can just use the jumper (or optionally wire the jumper to a manual switch).

A message I just received from Apacer Dear Stefaan, More information on the WP function. Apacer product is programmable for WP. The WP pin is low active, so WP wll be activated whenever the pin is asserted low. The system board, however, needs to have a WP controll logic to enable/disable WP. Not many M/B's supports such a control logic, so this is kind of a desgin-in feature. Partial WP by block is not supported by the current firmware version.

I understand this. But as i see this, this special device has one pin that it put to ground enables write protection. So what i that was: why not put this adapter between it that does nothing but connecting all pins from the device to the motherboard directly, except one, #30, which can be set to ground or whatever using a switch.

I just got word back from PQI, I should get a data sheet in a couple of weeks. It won't be availiable until May though :( ### snip ##3 Dear Lynn Yes, we are now ready to present the first model of our Secure Disk on Module product; it will be formally launch to the market in May, this product is perfectly for those applications, which just likes you mentioned. PQI now is the market leader in Taiwan and Europe for this type of product, Secure DOM is our latest DOM product; it also being asked by many of customers who just like you since one and half year ago. Because for the password type DOM can not satisfy with their needs anymore. I will send you the datasheets of this product in the end of this month, because PQI will close for the Chinese New Year from Feb. 9 to Feb. 17. After you go through those product descriptions, I ensure you will be very interested to this wonderful DOM/HDD solution.

The ATA interface is a complex combination of registers that require read/write access to send commands and recieve status/data from the ATA device. To install a "write-protect device" between the motherboard and an ATA device, you need something that understands ATA at the application level, and returns some sort of error for logical write commands.

The whole question of write-protecting a hard drive is a moot point if you people would just use scsi equipment. The jumper for write-protect is clearly marked, and even the non-technical people could connect switch leads to the pins, given the correct mini-jumper connector. I suggest dusting off your old Mouser catalog and putting it to some good use :) I got so many of those old scsi drives that I'd love to boot from, then power down, because I don't need the indoor chainsaw :) Personally, I prefer secure network loading of packages off my fileserver. And why don't you people use cdrw? Rewriters are like $50 for a bottom of the line, no-name, ide burner. Who's compiling cdrecord.lrp?

Your right, my BIOS won't acknowledge the disk with the write pin (#23) 'disabled'. I guess if you wanted to go far enough, you could put a solid state time-delay relay on the power switch and set it to shut the write pin off after 'x' seconds ... not too practical though.

I can attest that this affects the BIOS too ... no write, no drive! Thanks for the info ... I've been intending to atleast try it for quite some time in any case.

Jeff, I'm reading through the CF 1.4 specifications. http://www.compactflash.org/cfspc1_4.pdf I'm starting to wonder if true ide mode will work with PQI's write protect CF card. From what I can understand of the CF specifications, it will depend on how PQI implemented write protect.

I probably shouldn't have put it in there, sorry. I remember a long thread with some people trying this a couple of years ago though, did anybody ever have any success??? If my memory serves me right, there was a problem with disk-corruption errors if the system tried to write to the HD. It wouldn't be much trouble for me to try this if your really interested though. A less frustrating way of trying would be to wack a piece out of wire #23 and simply switch to another cable to write. I'll give it a try, I need to do some soldering today anyway!

CORRECTION The 40-pin is regular IDE connection, the 44-pin is for IDE w/power built-in to the cable (laptop, microboards, etc). Sorry for the braindead statement there.

It appears the error messages on that page refer to BIOS calls from the device(s) when it thinks it _should_ be able to write to the device. It only happens when the write-protection is on. > Let them know this is what you would like. Who knows, maybe they will > build it. Yes, I think I will. I've used similar products, but they are European and though the products are fine; ordering, shipping and paying in another denomination is inconvinient. I prefer the 44-pin products because many of the 486 and P1 products limit the floppy BIOS to 1.44M. Using the 44-pin bus ensures that there will be no problems at all, IMHO.

They may need to make some changes to their adapter to accommodate the write protect function of the PQI CF card.
