Hi all, My setup : ---------- - Zeos Pentium 90, 64 Mb ram, Stealth VRAM 64, built nov 94. - no IDE disk, 1 IDE CD-ROM (Acer 50x) - controller BusLogic BT-946C (PCI to SCSI-2) (firmware 4.21, BIOS 4.84) - 1 internal SCSI disk IBM DDRS-34560 (firmware S71D) This system ran RedHat 5.0 for years without trouble. My problem : ------------ I wanted to go for Mandrake 7.1. I downloaded the 2 ISO (md5 checked OK) and burned them. Full system backup and boot from floppy (as this old Pentium can't boot from CD). Install run fine until it tries to partition the disk. The error text is : "error : no valid device were found on which to create new filesystems." >From a bash console, I try to run "cfdisk /dev/sda", it fails. However, in another console, the controller + disk are recognized by the kernel as /dev/sda. I tried : --------- Installing Mandrake 7.02 works perfectly, I tortured the disk setup, and nothing seems to be broken. I then tried to upgrade to Mandrake 7.1, but the failure happened when it tried to check the disk partitions. There is no error message, it simply loop over SCSI controller detection. IMHO, it looks like a bug in the handling of my SCSI setup in 7.1. Any hint welcomed. :-) Charles -- Judge Thomas Penfield Jackson says : Falsus in uno, falsus in omnibus Charles Bueche <[EMAIL PROTECTED]>
