ahci.sys

[victor]

where can I download the dos cdrom driver ahci.sys ?
I can't find a link.

Reply:

I want to boot from dos because I use a dos tool.
I cannot boot from floppy because my usb floppy drive needs a windows driver.I must boot from cdrom.
Booting from cdrom succeeds but I can't read my cdrom.
I think windows 98 drivers will not work with dos.
I've already tried gcdrom.sys and xcdrom.sys but it didn't work.
I think I need the dos driver ahci.sys because i've detected my cdrom controller is a SATA AHCI controller.

There are many CDROM drivers for MSDOS.

Get a Windows 98 SE boot floppy disk and it will have several on it - boot it up to test if it works with your cdrom. It's very likely that it will.

Windows 98 SE drivers on the floppy disk are dos drivers, but one aspect you will find is that when you boot from CDROM the driver will reset the cdrom
and it can stop the boot process.

You can use a Virtualbox machine to run the dos file in - if you explain the process then you may get better options.

Did you try looking at bootdisk.com or allbootdisks.com

I've looked add the windows 98 SE floppy image of the site allbootdisks and it contains several cdrom drivers:
oakcdrom.sys (for ATAPI cdrom)
different aspi drivers for SCSI cdrom's
btdosm.sys (for multimaster SCSI cdrom)
btcdrom.sys

but no ahci.sys

I've also looked to the windows98 image of another site w/o success

Just did a Google search for the file you were looking for. Seems to be plenty of options for getting it.

Almost every single link I found for it was the same dead hp.com link.

[foxidrive]

This is another option it seems. Google for gcdrom.sys

http://help.fdos.org/en/hhstndrd/base/gcdrom.htm

I wasn't aware that the SATA interface would be an issue - sorta thought the BIOS would translate it.

Hi ShadowThief,

Thanks for your link to HP.I've downloaded ahci.sys and it works!

[mwstroberg]

I just downloaded and tried out ahci.sys in order to try to get a SATA optical drive to be readable in DOS. However, there does not seem to be any documentation as to its command line parameters. When I run it with just the /D:CDROM argument, it apparently only looks at the ports on the first SATA controller, and does not see the optical drive, which is on a port on the second controller. Is there a way to tell it to look at a controller other than the first, using a command line argument similar to the /Cx argument for gcdrom.sys? Any help would be appreciated.

I don't remember any driver named "AHCI.SYS", but i think i remember one named "AHCICD.SYS", so no guarantees for the following:
If i remember right, then the "AHCICD.SYS" has an optional parameter "/C:<#AHCI-Controller>", where "<#AHCI-Controller>" is a digit from 0 to 9.
If you leave out that parameter, it typically only searched the first AHCI-Controller.

So the line in your "config.sys" might be the following:

Code: Select all

DEVICE=AHCI.SYS /D:CDROM /C:1

Hi penpen. I had already tried /C:<#AHCI-Controller>, but no matter what number I used, it only scanned the first controller (0). There must be documentation on this somewhere, but I simply cannot find it. Thanks for trying.
