Well, XFree86 often does run its BIOS emulator on the card, and yes, it may do a much better job. One could port that code to the kernel, but you'd still have to get to the kernel, and often the modern BIOSes seem to crash the (older) SRM BIOS emulators, so even with auto-boot or serial console, you'd get stuck... :-\ --Jay++ - Jay A EstabrookHPTC - LINUX support Hewlett-Packard Company - MRO1-2/K15 (508) 467-2080 200 Forest Street, Marlboro MA 01752 [EMAIL PROTECTED] -

On Mon, 28 Apr 2003, Jay Estabrook wrote: The SCSI hd and cdrom are detected, but it tries to spin it up immediately afterwards ... and seems to stop then. My symptoms were a stream of SCSI error messages related to the CDROM (unit 6), but not the HD. When I disconnected the CDROM, the HD was recognized and MILO was usable to boot from, which I proceeded to do. I believe that the problem is in the QLogic driver used in the MILO; if possible, work around it by isolating the CDROM on it's own SCSI bus, using another SCSI controller, say QLogic or NCR. I'm using the XLT MILO and finally can report success: the problem with MILO unable to spin up the disk was solved by setting a jumper on the hard drive (PARITY DISABLE). So booting using MILO works mostly, except that it doesn't do it automatically. E.G. I can boot the installed Debian/Linux on the harddrive with: MILO boot scda1:/boot/vmlinuz root=/dev/sda1 I also figured out that there is a boot image on the CD at sr0:boot/linux, however I didn't figure out what the exact command line is for booting the debian installer from CDROM. At least something like 'boot sr0:boot/linux root=/dev/scd0 load_ramdisk=1' doesn't work, since no ramdisk is found, and I don't find any that I could specify on the command line with 'initrd='. Finally, I had the following success running X from the XLT MILO: 1. Voodoo Banshee 2. ATI Rage 128 3. ATI Radeon 7500 I can now run X from the XLT MILO, 3d works aswell (if I use 16bpp, Voodoos hardware limitation). However I have to boot from CDROM, start the XLT MILO, enter the boot command until I finally can use my machine. So now I try to create a FAT partition, put MILO on it so I can use my Linux on the harddisk (which was installed using SRM, but luckily MILO understands BSD disklabels). Thanks, Max
