[SOLVED] qemu: "cdrom device has not been found"

Xeratul · 03-05-2011, 06:49 AM

Hello,

I run qemu windows 98se with :

Code:

qemu  -m 256 /applications/emuwindows/win98se.cow -soundhw sb16 -localtime -boot c -cdrom myiso.iso

however it says after ctrl + alt + 2

eject cdrom
"cdrom device has not been found"
change cdrom secondiso.iso
"cdrom device has not been found"

same story...

anyone would know what is the issue?

I'm pretty sure that Windows 98 needed you to manually load the CDROM device driver. It was not plug and play. You would have the same problem if you installed W98 directly onto a computer instead of a virtual machine.

thank you for your reply. Installing was fine, using the cdrom, however I never had to change the cdrom. Only at boot, when I load any kind of ISO using -cdrom isofile.iso , it works

however changing cdrom during the run, is not seen or working

is it a bug?

Put full path of iso in batch file.

I found that the errror

the cdrom device has not been found is when you wanna change the disk/fda/cdrom

PHP Code:



 
 
5. Changing a floppy and a CD-ROM image 
 
To change a floppy and a CD-ROM image, please use QEMU Monitor. To see the Monitor, press Ctrl-Alt-2 keys together. To go back to the guest OS, press Ctrl-Alt-1 keys. 
 
Please use slash instead of back slash in a QEMU Monitor. 
 
For floppy, 
(qemu) change fda filename.img 
or 
(qemu) change fda d:/tmp/yourfile.img 
 
For CD-ROM, 
(qemu) eject cdrom 
(qemu) change cdrom filename.iso 
or 
(qemu) eject cdrom 
(qemu) change cdrom d:/tmp/yourcdrom.iso

Under Qemu

change fda disk.img is no longer and not always working.
same for cdroms.

the solution is :

Code:

info block
eject sd0
change sd0 demo-disk2.img
