i am not really sure what's your reason for making such program but you could have done it without using tsr: mov ah,02 mov dl,":" int 21h mov cx,0 loophere1: mov dx,0 loophere2 dec dx,1 jnz loophere2 loop loophere1 mov ax,4c00h int 21h

some thing like this?? mov ah,0ah ; buffer keyboard input lea dx,parameter int 21h call nextline mov ah,09 ; display string lea dx,namefield int 21h mov ax,4c00h int 21h parameter label byte maxlen db 30 actlen db ? namefield db 28 dup('$')...

Can i hitch a ride.. :)

kindnumber9, we have the same problem. There seems to be limited resources when it comes to tweaking the different I/O ports. I had no problems when my OS was still Win98. XP is very protective of the system.

i think, all your program does is to terminate and return to dos..thats what int 21h function call 4ch does.. try removing "PUBLIC _start"..this might be the one that is causing the error.

i really don't understand what you want to do... but if you just want to display the content of the stack (say 56)..try tweaking these codes: push 56h mov bp,sp mov al,[bp] mov bl,al mov bh,al shr bh,4 add bh,30h and bl,0fh add bl,30h disp: mov ah,02 mov dl,bh int 21h...

the above code will clear the screen. add the following code to set cursor position. mov ah,02 mov dl,30 mov bh,00 mov dx,00 int 10h

i am not really a hardcore assembly language programmer but i would suggest that you use the assembler that suits you. and you might want to start with 16-bit, besides the site that you have been visiting/reading - http://www.joelgompert.com/OS/introduction.htm uses 16-bit code programming...

try this.. i don't have nasm but it worked with a86. mov ah,06 mov al,00 mov bh,07 mov cx,00 mov dx,184fh int 10h

I am also wondering how you were able to interface the 8088...

maybe you can start by studying the pin configuration of the microprocessor that you've got. you can start with wiki - http://en.wikipedia.org/wiki/Intel_4004 i had some experience with 8086/8088 systems. i will assume that 4004 system that you are trying to build is not too far off the...

i use a86..but i guess it only works for real mode. anyway, you can download it from this site: http://eji.com/a86/index.htm

there is this debug.com file that you can use. it will show you the assembly and the hex code. in your command prompt type "debug 'name of file' then type "d" (dump)

kazsemisonic: use a86.com, it's very easy to use. the code will be assembled into a com file. try to download it here: http://www.skynet.ie/~darkstar/assembler/ if you can't download it, post your email here and i will email it to you. Tack24: can i see your code

you are sending it through first register, why are you recieveing it through the second registert aren't you supposed to receive it on the same port??

hello.. just a thought. the price difference between a hub and a switch is relatively small (unlike before)...and so, i suggest that you buy yourself a 24-port switch for your 20 workstations.

another posibility is to loop your program in machine a, long enough for machine b to be able to collect the data.. this is just another thought..

hello. i am not really good at assembly language or any other programming languages, but i think what you are trying to do is not possible...correct me if i am wrong, you are trying to display "a" to machine b.. it will not work because the data you've sent will be lost before...

hello.. you 3com hub can detect a faulty connection, the LED will be of different color from the rest (usually red). faulty connection can mean bad nic, bad cabling or any other anomaly... if suspect that you had a 'bad nic' try swapping nic.. eugene

just a thought.. you can achieve 100mbps if your hubs can support such speed. but if you plan to buy new hubs, you have to consider first the size and complexity of your network...you might want to buy a switch instead. eugene
