Oops, man, was bad. I cannot see, this message is before after the another one I answered it 'cause my mailbox are fully unorganized. Again, my FreeBSD is 3.2. I'm old than the other members of this list and sorry for my english too.

It doen't show um on the >booting msgs too) You had both HD and CD-ROM atached to the same IDE controller. Try to back to older situation where the CD-ROM and HD worked. This can be IRQ, DMA or PORT conflits, Take care, man, 'cause after you put the sound card the CD-ROM simply stopped of work. Do you have another system that FreeBSD, one example: Windows 95, The three devices: CD-ROM, HD and Sound Card work fine within Win95. Search at the System Properties of the Windows 95, for you have knowledge about the correct ports, irq's and DMA address of the devices. So, after getted the correct adreesses, Compile the new kernel with these parameters. > > What is the right kernel configuration for this case?

One observation: Is not good to put the "signal cable" of your CD-ROM in the IDE controller of your sound blaster, Many UN*X systems are not good to handle these other IDE Controllers and/or devices correctly. So, try to back to the older situation: You have only a IDE controller with one or two IDE ports. If you have one port, the best way is you to put the Hard Disk as master and CD-ROM as Slave. If you have two, put bother as "master" Of course, you need to create the special device files under /dev directory. if your HD and CD-ROM are at the same IDE port. per example # sh MAKEDEV wcd0 --> this will create the eight possible partitions or ways to access the device. Give a look at the MAKEDEV script, I think is cd0 The CD-ROM device, usually is another, "wcd0a" or "wcd0c", Both of these devices are "symlink" to acd0a and acd0c, the standard CD-ROM IDE Device > OBS: would it have something to do with device sbpcd=iobase,type ????? :/) > Not, this is an owner CD-ROM interface, this is used when you have CD-ROM devices which cannot have 40 pins. >tnx... or THX... > What is this ? 8-) >nwerneck. > > >To Unsubscribe: send mail to majordomo@FreeBSD.org >with "unsubscribe freebsd-questions" in the body of the message > > Gustavo Pamplona - pamplona@uai.com.br Linux User: 137471 - FreeBSD User: FBSD042237 Linux Slackware 7.0 | FreeBSD 3.2 Release --------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
