On my system (brand-new AMD-486DX4-120), the error that I get tells me that the failure is occuring as the kernel is being decompressed. This would suggest that APM is *not* the problem, as the kernel (if it does have APM support) has not yet started to run. I have seen postings on this mailing list that claim that the problem is level 2 cache, level 1 cache, EDO RAM on a board that doesn't support it, or generic hardware instability. Some 486sx system boards do have cache. If this is the case, try turning off the cache and see if that fixes the problem. If it does, report it as a bug. ...and now for the soapbox... Given the type of problem you've reported, you might hear the infamous "hardware instability that doesn't show up when running DOS or older versions of Linux because the newest Linux makes your machine work harder" cop-out. This is a completely invalid argument, IMO. I've heard it several times (not in the message quoted above :). If I can run older versions of Linux, and a new one shows up that doesn't run, then I claim that the problem is in the new software. I've already had this happen once. I ran Linux 1.0.8 without problems on a board with a Cyrix 486DLC-40. When I installed 1.2.8 I started getting frequent, random SIGVEC errors. These would often bring the system to its knees, forcing a power cycle. I heard from several others who had the same problem, but the only help we ever got were suggestions that we should buy new motherboards. I finally gave in, because I wanted a math co-processor and a faster CPU, and I wanted to get the *&^&@#%^! machine running (and because I'd finally saved up enough money). So, I have just purchased my new motherboard (with the AMD chip), and 1.2.8 runs very well. I have not seen any SIGVECs at all since the upgrade. Now I'm being told that I can't install Debian with the 2.0.x kernel because my hardware is incompatible? This just doen't make sense! >>From what I've seen in the few days I've been on this mailing list, there are several people out there who are having trouble installing Debian because of conflicts with the cache. Of those, several are running an older version of Linux successfully, or have managed to install the system by temporarily turning off the cache, and have no problems decompressing the kernel from the hard disk. Sorry if I sound a bit peeved about all this... ...but I am. Chris -)----- -- Christopher R. Hertel -)----- University of Minnesota [EMAIL PROTECTED] Networking and Telecommunications Services
