Replace the motherboard, controller, and IDE drive all at the same time and get rid of the old ones. I had an IBM drive go bad this way, and the replacement WD Caviar went bad in exactly the same way. It is not just Linux, although Linux was first to detect the problem. OS/2 would give me a black screen, then later even the BIOS failed to load LILO. Different drives, same problem. Different controllers too! What I think happened: an accident with a screwdriver that destroyed an IDE board also zapped the motherboard. Everything plugged into that slot was slowly destroyed - maybe I burned out a capacator. So yes, the drive is bad. Your motherboard/controller fries it. -- Albert Cahalan albert@ccs.neu.edu ------------------------------ From: rob@pe1chl.ampr.org (Rob Janssen) Subject: Re: mounting scheme for cdrom suggestion Reply-To: pe1chl@wab-tis.rabobank.nl Date: Thu, 14 Dec 1995 14:30:05 GMT In aeb@cwi.nl (Andries Brouwer) writes: > LABEL=`cdlabel` `cdlabel`?

I think this could not easily be done, because of minor number allocation scheme Linux uses (the 1st recognized SCSI tape gets minor 0, the second 1, the third 2 ... The similar scheme works for disks too. I think this is because of only 16-bit dev_t. Linux kernel prepares to move to more wide dev_t (look at linux-1.3.45/include/linux/kdev_t.h).

It seems to have severe problems compiling stuff with asm()s (something about incompatible constraints). For example, it doesn't like SVGATextMode, or kernels 1.2.13, 1.3.18. GCC 2.7.0 seems to be safe, and I'd stick with that, I don't think -O2 breaks it either. You could always write the IO bits in pure asm and link those in seperately (makes porting easier too since you know which bits have to change. If that's a worry of course...) You should also check the ioperm() call since your program as it stands will fail even if it compiles - you need to request (as root) privilege to access the relavent IO areas.

I love it, and it does what I need it to do, but I think that we are moving into the next generation of network authentication and encryption with the IPSEC/AH/ESP/Photuris specs. Really, encryption done at the network level rather than the app level has a lot of advantages, and I am happy that Kerberos was able to pave the way for this. (Sorry, I see Theodore T'so's posting right after this article, so I get nervous. I really do like Kerberos. Really.) Nonetheless, if and when all network data streams are IDEA- or DES- (shudder) or whatever-encrypted, and when key management becomes central to proper network functioning, then centralization of these resources has a lot of advantages, not the least of which is that eventually you can imbed the calls into the kernel and reduce two IPC memory hops within the machine, which is important on a 100Mb Ethernet or x00Mb ATM network. Plus, my Kerberos apps have DES code. My xntpd suite (if I am not mistaken) has its own DES code. My system has its own (crappy) crypt routines. PGP, God bless it, has its own. As encryption becomes more mission-critical, it just seems to me that there should be a better way to do it than each individual app implementing all of these standard encryption algorithms separately. I would like to get some feedback on this, especially to see if people would be interested in having a discussion concerning this via a mailing list or, if interested, we could meet on my IRC site at some predetermined time.
