Is your card an ISA card? How much system memory do you have? If it is an ISA card and you have 16MB or more of system memory, then you can't get to 16bpp because an ISA bus can only address 16MB of memory at one time, and XFree86 currently requires linear addressing with that chipset. I'm no expert in this field, but I've experienced much pain in trying to get higher than 8bpp with XFree86 myself. I purchased a Cirrus Logic based ISA card with 2MB of DRAM. I have 24MB of system RAM. This chipset also requires linear addressing. So I couldn't get to > 8bpp either. But, using the bundled Windows drivers, I was able to exploit the full potential of this card (24bpp at 800x600 I believe) from Windows. Kind of annoying, really. You can always try out the commerical X servers (MetroX is one ... I recently read somewhere that it's being included on InfoMagic's LDR, which is only $50!!). What I'm gonna do is give my system a major overhaul ... I'm gonna yank out the motherboard and stick in a Pentium one with PCI slots (ISA video sucks anyways). There's no linear addressing problem with PCI cards, I believe. ============================================================================== Arcadio Alivio Sincero, Jr. Undergraduate Computer Science Major/Linux Enthusiast/Competitive Bodybuilder email: [EMAIL PROTECTED] WWW: Not available yet -- still looking for free webspace!
