    No, his "mod" was written from scratch using the official grub4dos source code.

    The source has not been published since zsmin has put allot of work into it, plus it would mean there would be new versions of the GRLDR floating around with no improvements whatsoever and a new author name. On top of that it would then render encryption/decryption useless since they would be in plain sight to everyone.

    I think zsmin did mention that you (or maybe it was someone else) asked for the source before via a private message, I'm not sure if he replied but I know the answer was no :eek:

    Simple answer, he wrote it himself! Ohh. btw.. I can understand zsmins decision not to publish his code. After a lot of work on my kernel driver it became more and more to a rootkit ( 'cause of the hiding feature:D ) and I also won't publish the source code anymore. So if u still want any source code your best bet is the kernel mode driver here on mdl.

    But ur kernel file has only support for acer cert as i know, as u can see in the source code, grldr is 4 every cert (copy /b part1 cert part2) ... i think u need make ur kernel file to have a way use other cert file

    Hmm just think. The slic is embedded so either recompile the driver or, write a simple app which replaces the slic in the .sys file ( don't forget to rebuild the digital signature )

    Yes, think it is a secret. Why did you so interested? If you are an experienced programer you may develop something without using someone's work, you are showing an strange behaviour...:eek:

    I can tell you that when zsmin started work from the GRUB 4 DOS source he didn't know a whole lot. He learned about tables and relocating data and allot of it was trial and error and allot of debugging. I'm sure that may be somewhat the same with secr9tos's source code for the driver, allot of time was put into the projects so they don't exactly have to give anything out to start with.

    I look at it as if these guys can do it and the projects are closed source then rather than trying to decompile anything simply start where they started and learn to do it yourself. Taking someone elses source even if its open source without any knowledge of how it even works won't achieve you anything but a headache and possibly a bad rep. So knowledge may be power, but it's where that knowledge comes from thats the key.

    i don't, if someone have great project he did, that can spare time to other's so he need to PUBLISH it to save other's time. this is the ^moto^.
    to make project fast u need sometime's other's code. make it by ur own with lot of time no help u so much

    The thing is you likely don't understand table relocation, the standard GRUB 4 DOS code or anything else thats required to improve on any source. So even if published not many people could actually do anything with it other than compile it with their named tagged onto it, but then why should he release the sourcecode for that to happen -- and that would happen. So it wouldn't save you any time since you wouldn't understand how it works, where as if you built it ground up then you would know exactly how it works and is something you can call your own.

    Another question would simply be why do you want the source if whats provided already works perfectly fine? Theres nothing to improve on which you could understand without knowledge of table structures and even then you would be working in code which is alien to you.

    With the driver secr9tos has provided pretty much a working "proof of concept" (it actually works well) which people can build off. With the GRLDR the source is already online (GRUB 4 DOS) all you have to do is learn about table relocation and implement functions to relocate/insert tables (a SLIC).

    Stop asking, he is not gonna share his source. I've only been gone two months, don't the mods lock useless threads anymore ?
