I want to install FreeBSD on my computer. I downloaded the 4.3 disk image, burned it on CD-RW, and proceeded. Several times. Actually, I consider myself to be an installation expert now, being able to breeze through setup in under one minute. Alas, I doesn't make me any wiser when it comes to the problem. PROBLEM Take a look at output of debug console after copying files starts (square brackets mine): [...some filenames here, not very much, just few seconds worth...] ad0: WRITE command timeout tag=0 serv=0 - resetting ata0: resetting devices .. ata0-master: DMA limited to UDMA 33, non-ATA66 compliant cable [ The above 2 lines appeared 0 or more times. I am not sure whether the motherboard supports UDMA-66, but it turns out that I don't have an appropriate connecting tape. The device probing reported VIA 82C596 ATA 33 controller anyway. Later on I turned UDMA-66 mode off suspecting that it could be the cause of problems. Unfortunately, it was not. ] ad0: WRITE command timeout tag=0 serv=0 - resetting ata0: resetting devices .. device dissapeared! 3 done ata0-master: timeout waiting to give command=ca s=d0 e=00 ad0: error executing command - resetting ata0-master: timeout waiting to give command=ca s=d0 e=00 ad0: error executing command - resetting ata0-master: timeout waiting to give command=ca s=d0 e=00 ad0: error executing command - resetting [hang] [ Shit hits the ventilator. This "device dissapeared" (original spelling) stuff is horrifying: after rebooting BIOS doesn't see any of the devices on primary IDE controller. The only remedy is to power off and on. ] HARDWARE motherboard: FIC VB-601-V, Apollo Pro+ chipset for Pentium, ATX primary master: Fujitsu Picobird 13 MPD-3064-AT, 6181 MB primary slave: ATAPI CDROM (LG) secondary master: IBM Deskstar DTLA-307030, 29315 MB secondary slave: none * By the way, is it better in terms of performance to have 2 hard disks on one controller and the cdrom on the other? I did not mess with secondary master, as I normally boot from it (booting device order in bios is set to floppy - cdrom - ide1). BIOS (AMI) is reasonably new, I flashed it in 2000 I think. It is called qc617.rom if you are interested. I fiddled with various settings, but to no effect. Well, once I managed to get kernel panic but can't remember exactly how. Power management is off so the computer doesn't fall asleep during install. I also toggled boot sector virus protection, but as FreeBSD does not depend on BIOS to access the disks and BIOS doesn't notice when FreeBSD writes MBR it doesn't seem to matter. * At this stage, noble wizard, you surely know the solution. Details follow for your reading pleasure. Hard drive geometry as reported by BIOS: 13 410 / 15 / 63 59 561 / 16 / 63 Hard drive geometry as we normal people are expecting to be given: 788 / 255 / 63 3737 / 255 / 63 KERNEL CONFIG I just disabled all network and all SCSI drivers, since I have no such devices. PARTITIONS (slices, that is) on primary master - recent set 1 FreeBSD 64 228 KB cylinders 0 - 7 2 unused 3 FreeBSD 2 192 872 KB cylinders 8 - 280 4 FAT32 LBA 4 072 477 KB cylinders 281 - 787 The first one is for root, as you undoubtedly guessed. The second is divided as follows: swap 125M /tmp 125M /var 125M /home 250M /usr the rest * By the way, how many partitions can you have on a slice? what about a, if root is somewhere else? MEDIA First CD, then DOS partition ( ad0s4 ) where I copied everything from CD. __________________________________________________ Do You Yahoo!? Get personalized email addresses from Yahoo!
