TurboLinux has the ability to install on a DAC960. (www.turbolinux.com: Get only the *server* boot/extrawh floppies, Workstation only has RAID on the CDROM) I'd be happy to explain what we did to make the installer work: * dac960 is a module * /dev/rd* automagically mknod'd for partitioning * mkinitrd run to make sure the module is available Of course, you have to pre-build the RAID device with the Mylex tools. However, it seems like more is wrong than a simple install problem. Wish you luck! Ciao! (also: [EMAIL PROTECTED]) -- Eschew Obfuscation.

Re: Botting a Mylex DAC960 RAID controller
a quick fix may be to install the distribution onto a non raid'd drive and just copy it over once the raid is setup. this is how i setup my (software) based raid servers.. installed to 1 partition, made the rest of the partitions mirrored, and just cp -a'd the files over after i made the raid arrays.(resized the root partition too) Filesystem 1024-blocks Used Available Capacity Mounted on /dev/sda1 839599 126369 669857 16% / /dev/md0 1189050 786848 340759 70% /usr /dev/md1 1484447 939148 468595 67% /users /dev/md2 513082 349434 137146 72% /var /dev/md3 147666 161 139880 0% /tmp /dev/sdb1 839599 272200 524026 34% /stuff might save you a lot of pain & suffering with installing directly to a raid array from the start. does the mylex raid controller support booting linux off a raid array? from what i read the root partition cannnot be part of a raid array without some crafty configuration. nate On Mon, 22 Nov 1999, Enrico Zini wrote: zinie > zinie >On Mon, 22 Nov 1999, Jean-Yves BARBIER wrote: zinie > zinie >> > > Try `mem=256M' instead. zinie >> > > Please let me now how the Mylex performs ... zinie >> > No luck: the installation keeps hanging asking about colors. zinie >> Try `mem=255M' instead. zinie > zinie >Fine, I'll give it a try tomorrow. zinie > zinie >Even if it starts, anyway, the problem remains: raid disks on DAC960 zinie >aren't neither EIDE nor SCSI disks, and /dev/rd* devices are not created zinie >in the normal boot floppies; a quick hack I thought of is to change the zinie >major numbers of /dev/sda* devices, so that Debian installation will zinie >believe it's coping with normal scsi devices; I'm not satisfied with it, zinie >however, since normal devices for it should be named something like zinie >/dev/rd/c0d0*.

Fine, I'll give it a try tomorrow. Even if it starts, anyway, the problem remains: raid disks on DAC960 aren't neither EIDE nor SCSI disks, and /dev/rd* devices are not created in the normal boot floppies; a quick hack I thought of is to change the major numbers of /dev/sda* devices, so that Debian installation will believe it's coping with normal scsi devices; I'm not satisfied with it, however, since normal devices for it should be named something like /dev/rd/c0d0*. No, that's not on a Sun. BTW RedHat 6.0 used that c0d0* convention right, so their boot disks can be worth a glance for `ideas' O:-) Another problem is the Asus mainboard has an Adaptec UW SCSI controller built-in that has been disabled on the BIOS configuration. Sadly, just the SCSI bios has been disabled from that board, and the Linux Adaptec driver hangs when it finds its controller. The only way I found to avoid Debian boot disks try to load Adaptec drivers, is to make a new kernel. No use were the adaptec boot disks from http://www.debian.org/~adric/aic7xxx/, and even RH6 hung when trying to initialize it: RH6 can only be installed in 'expert' mode, on that machine. Not that I'm afraid of expert modes, anyway. Read you soon! Enrico

I can't see why syslinux reports having less than 608Kb of base memory. Well, I *can* see why, since the base memory is in fact less than 608Kb (I tried to also boot with a dos floppy, and the results are the same), but I don't know who's eating that ram. I'm trying with a RedHat 6 (The server will need Debian, anyhow), and I had more luck: it didn't require a custom kernel and had a module for the DAC960. It seems to hang, however, when formatting the drives, when a disk is reported dead. Perhaps we have also a problem with the disks, we'll see. Redhat installation hangs when formatting/mounting. I'd need more data on that base memory requirement complained by syslinux. Anyway, DAC960 seems to be a good controller, and Linux support seems to be the good Linux support I always found with Mylex devices. I'll be able to tell more that impressions when I'll be able to have it running. Read you soon! Enrico

Botting a Mylex DAC960 RAID controller
Hello! I'm trying to install Debian slink on a double pentium 2 server with a Mylex DAC960 RAID controller with 3 IBM UW2 9Gb disks. After compiling a custom kernel for the boot floppy and making it boot and see the DAC960, I found that the Debian installation hangs: it gets stuck asking me if I have a color display (the cursor stops moving). The server has 256Mb RAM, but I tried to boot with Linux mem=256 and it dumped registers. Syslinux, instead, complains that low memory is lower than about 600Kb, and asks me to boot it holding Ctrl. Is there some custom boot floppy to try with? Has someone installed Linux in a DAC960-only environment? Read you soon! Enrico
