 first of all i thank you for these great infos and tutorials . i really admire you .
i have a request which i would be very thankful if you answer it ,
that is would you give a full explanation on FAT itself , i mean fat table, there are couple of reserved places and stuff which i couldnt find any relevant info about them , in each tutorial i searched, they kept saying they are reserved, the question is what are there reserved for and whats the idea behind it ?
i would be very thankful if you do me a favor and have a topic on this.
Best Regards

 In order to get the Hello World bootloader to work I had to add the lines
MOV AX, CS
MOV DS, AX
MOV ES, AX
MOV SS, AX
before putting HelloString into the SI register

 Dear Taj,
The perfect notes are combinations of text & video,i am happy to say that text is perfact but it needs some extra ppt or graphical or diagramatic approach.

thank you

 Hello Viral,

I am a grad student at Texas Tech and I personally found your blogs to be really very insightful. So, thought of dropping you a quick note to thank you for the same.

Also, I have a quick question for you. Since, I am also planning to design a small OS for my x86 machine, can you please suggest me some good implementation book on OS? I know there are many books on OS concepts, but I want one which talks more on the implementational aspect.

Thanks again for all your help and I am really looking forward to hearing bak from you.

Shubham

 Hello, could you please please do some of your C stuff in Assembly. I know your OS is in C but mine is in Assembly and i can't convert C to Assembly. It gives me the biggest headaches.

Thanks

 Hi,
Great OS Stuffs.
Do you plan to release the source code for the Taj OS?

Best Regards

 HI ,

great articles on OS , truly neat

however i've discovered something rather weird ...which is that the third boot loader example which is supposed to print a full null terminated string "Hello World" to the screen , Does NOT seem to work !

what makes this even more strange is that when i load this boot sector using bochs (which is an 80x86 emulator) the code runs absolutely flawless as expected , truly weird ?!

did anybody else notice this same debacle ?
btw i've tried nasm as well as yasm (all producing flat bin files) then raw written to a USB key using DD on linux

from what i've gathered some far is that any code that references memory locations such as "mov si,your_data" seems to return null memory locations.

i should also mention that the previous 2 examples worked , also worth mentioning is that the 3rd was assembled as is.

cheers
