If you go here http://board.flatassembler.net/topic.php?t=2164&start=50
in my code for "CdPod" there is some fasm code for programming atapi (CD). Note: I was called "ASHLEY4" then. |

No, But you can downlowed "Dex4u" (my OS's)
In it is my fully working ATAPI driver, writen in fasm, you can get the OS to try here: http://falconrybells.co.uk and you can ask any ? here: http://dex.7.forumer.com/ about the code etc NOTE: There is two parts to the atapi driver part 1 "Ata_Atapi16" which gets the Drive and port and part2 "Ata_Atapi32" that is the driver, part one is run in real mode and part2 is run in pmode. Hope this helps. Last edited by Dex4u on 02 Jun 2005, 18:41; edited 1 time in total |

In your Ata_Atapi16.inc
WriteCommand1: mov dx,0x6 add dx,word [port] mov al,byte [drive] or al,0xef out dx,al mov cx,0xffff mov dx,0x7 add dx,word [port] I have a question about "or al, 0xef"... I think that it should be 0xaf? Port 176h: Drive selection port 0Fh - Reserved 10h - Master/ Slave (0/1) 20h - 1 40h - RESERVED (0) ??? But 0xef and 40h=40h!!! 80h - 1 |

Here is the standard that is the best guide for atapi programming
http://www.t13.org/project/d1410r3-ATA-ATAPI-6.pdf If you go to index number 127 (page 113), you will see info for "identify device" (ECh), if you look at Device you will see the all fields other than bit 4 are either "na" or "obs" which means they are not used. Also if you goto index number 149 (page 135) you will see "identify packet device" (A1h) also if you at device you will see the same as for (ECh). The first command (ECh) is test for Hdd and the second (A1h) is for cd/dvd. |
