I have compiled the kernel, taking care to choose CONFIG_ISO9660_FS, CONFIG_PANASONIC_WHATNOT, and CONFIG_SOUND. Upon boot, the kernel reports that the soundcard is detected; however, no CDROM drives are reported as detected. I am curious as to what I have to do in order to mount a CDROM under Linux. I attempt to use the command "mount -t iso9660 /dev/mcd0 /cd0" but that returns "mount: wrong fs type, /dev/mcd0 already mounted, /cd0 busy, or other error". I have also tried using "msdos" as a filesystem (as it is an msdos cd). This did not work either. I am not entirely sure /dev/mcd0 is the correct device; if it is not, what is? Also, how do I know if the kernel knows my CDROM drive even exists? The patch applied w/out any rejections, and I have the exact model the author reported he used with the patches. Any help would be greatly appreciated. ------------------------------ From: cmay@titan.ucs.umass.edu (CHRISTOPHER M MAY) Subject: Re: QIC-80 driver and IDEK 5217 monitor Date: 28 Nov 1993 06:24:46 GMT Erik Mugele (erik@csn.org) wrote: : I have a friend who is getting Linux up and running.

I often get I/O errors for no apparent reason. Doing anything major that uses the DMA will crash a backup or restore which is functioning in the background. One must still use DOS to format tapes. I haven't had time to get DOSEMU working to try CMS tape utils to format under DOSEMU. I know C but not C++, and I am pretty new to UNIX operating system programming. I am sure that there are others out there that know far more about the status of the tape driver than I, and there is a good chance that I am doing something wrong. I _have_ been able to backup, restore and verify using tar and diff for verify (is this correct method for verify???) Any info about new developments, releases, of ftape would be appreciated. : 2.

The Xfree86 people claim they must figure out/implement code to "put the RAMDAC (a part of the video _card_, not the monitor) into a special clock multiplexing mode", else it will overheat and die. They probably will implement the changes needed and quite possibly soon, I guess. There is a safety limit coded in to Xfree86 which blocks those clocks from being used. (Don't defeat it if that is the case, there has been a big thread about this with the Xfree86 people, and don't number your clocks with bogus/untrue numbers (e.g. clocks 1 2 3 4 5 6 7 8 ...) like some Xconfigs do). But getting a card which is self-destructible sounds like a _BAD_ idea! It speaks VERY POORLY of its design. A few extra logic gates would be all they'd need to add to protect it. Like $5 (extreme maximum overstatement!, probably much cheaper) on a >$100 card. That would be a good idea to protect people's investment, but I guess they just don't give a d*mn, or want people to have to buy new cards. ALSO, IF SOMEONE HACKS ROOT ON YOUR SYSTEM (ITS PROBABLY EASIER THAN YOU THINK, UN*X SYSTEMS ARE IN GENERAL NOT THAT SECURE), it is bad enough they can destroy your data, and misuse your system resources, but being able to destroy hardware is more than a few degrees beyond the utterly intolerable!

Gate each IRQ onto the bus with one section of the 74LS241 as follows. First power the chip by wiring pin 10 to ground and pin 20 to +5V, which you can find at a bypass capacitor on the board. If you reverse the polarity, you'll know by the resulting smoke! Break the existing IRQ connection. Usually you just remove a jumper. Wire the IRQ from the 16550a to pin 19 (high-true driver-enable) of the '241. Wire pin 5 (driver out) to the backplane IRQ of your choice, usually at the jumper. Wire pin 15 (driver in) to +5V. Tack a 330 ohm resistor between ground and the backplane IRQ, on only one of the boards. The 74LS241 can dump at least 15 ma into the resistor. The other seven sections in the chip are not used. Cut off all the other pins. Don't try this with a CMOS driver like 74HCT241. I chose the pin 5 driver because it's far from the supply pins, less likely to short. If you look at the top of a '241 with the numbers right-side up, pin 1 is at the lower left, usually marked with a dot. Pins are counted counterclockwise around the package.

I finally made sure all was conected properly again, and booted the floppy for Linux (Slackware) and everything works perfectly. In fact, I am using it now. Only things I am working on now are getting to the D: (of C:, D: & E:) dos partition on the drive on the primary adapter (WD1007).

If youhave a look for original IBM serial cards you will notice that there is 74LS125 ( tristate driver) which is the driver for the bus , not the UART (16550a or eqv.) Usually the tristate function is controlled with OUT2 pin from the UART. With little hacking you could use this chip , because it is already there. Of course there those modern chips having 2 UARTs and LS125 inside of them, then you must use LS241. I have been using the diode or-circuit more than 1 year, using AA119 germanium diodes and 1 k pulldown, 5 ports to irq 3 and 2 to irq 4. It really works.
