What does the /etc/X11/X point at, and what does the configuration file look like? Sorry, but I can't tell you. The only XF86 "driver" which I have found to work at all with the card is the generic XF86_SVGA. Using that module results in the behavior I described previously. Haven't tried the generic VGA module. The unadorned straight VGA operation at the beginning of RH installation works fine, since I can get to the point of configuring XF86 in the RH Linux 6.2 graphical installation process. Attempting to install ANY of the ATI Mach64 - Chrontel modules results in a blank monitor display, regardless of the amount of memory specified or the display resolution selected, requiring a hardware reset of the machine to permit restart of the Linux installation process. My suspicion is that the problem may have something to do with the "memory aperture" feature of the ATI Mach64GX chip which my board has. There is no jumper available on the board to enable or disable that feature. ATI claims the feature is "off" by default, and that special ATI software is required to turn the feature "on". Additionally, there is no jumper to enable or disable the board's "fixed vs relocatable" video port addressing. "Relocatable" appears to be hardwired "on". There are no jumpers on the board with which to set either IRQ or base address. As noted before, the card works fine with Windows 98. Thanks for your interest! Sorry, but I can't tell you.

Can you try making /etc/X11/X point at /usr/X11R6/bin/XF86_MACH64 (make sure to install it first) and create a standard XF86Config file with Xconfigurator? Tried pinstripe with it? Have you tried not specifying any clockchip? Sorry for the delay in answering! Been trying to get more detailed info than is available in the card manual from ATI. Turns out this card is pseudo-PnP. Can't manually set IRQ or memory addresses with jumpers on the card. Have tried installing with and without autoprobe and with and without specifying a clock chip - no dice. Works - sort of - using generic VGA device driver for 640 x 480 pixel resolution. opaque moves are painfully slow. Afraid I don't know what "pinstripe" is, nor how to use it. Based on my few month's experience, it appears Linux doesn't support ISA PnP cards - of any variety - very well. Only cards I've had any success with are PCI - one Lucent-based winmodem, and one ATI PCI graphics card. My ISA sound, NIC and graphics cards just don't sem to be supported. Thanks for your continuing interest. Dick Thompson Pinstripe is the 7.0beta , which was released a couple of weeks ago. I avent seen a ISA graphics card ever (my first PC in 93 had VESA localbus, the PC I bought in 95 was PCI) but I don't think they use plug and play - I think they are designed for a standard IRQ and IO so I would rule out that problem. They would be rather slow (ISA is sloow and shared), but you should get higher resolutions at least. However, I think I'll close this with unsupported hardware... Hint for mobing on is looking for a way to turn of the memory aperture in the BIOS. Most ISA networking cards and some soundcardsshould work nice, though - try sndconfig. I'm disappointed. It's disingenuous for Red Hat to claim cards are "undupported" when both Red Hat's own "Hardware Compatibility Lists" and the XFree86 organization's Web sites claim ATI Mach64GX cards are indeed supported, with no disclaimers for ISA vs PCI, or ISA-jumpered versus ISA PnP. Red Hat's own installer offers the option to install device drivers for these cards, again with no disclaimers. Whether or not these cards are "old", Red Hat claims to support them. Same for my old Ensonique Soundscape S2000. Red Hat's installer offers the option to install device drivers for it, but the device drivers loaded do not enable the card's MIDI functions. I'd appreciate some honesty in advertising from Red Hat. I realize you have no control over such matters, and I appreciate your help. Perhaps you will be good enough to pass my comments on to your marketeers and corporate heros. They need to understand that deceptive sales practices will, in the long run, sink them. Thanks again for your own courteous, professional help! Dick Thompson I was more thinking of your BIOS - the OS/2 hole between 15 and 16 MB needs to be off. As for MIDI support for the Ensonic, I have no idea - I just develop Xconfigurator(and quite a few other thing, but nothing sound-related). Read the kernel docs for more information (/usr/src/linux/Documention/sound) for limitations on the driver. Have you tried looking around the net for information on your card? If you can make a working configuration manually, it may be possible. BTW: Does it crash your computer totally? (network included) when starting? |
