Sudden failure of BIOS to detect new harddisk

view full story

http://forums.opensuse.org – I have problems with my acer aspire M1201. I have added a 2GB RAM beside the 1GB stock RAM. Currently I have reformatted my stock Hitachi HDD 160GB and I have added another HDD in which it is a Samsung 500GB HDD SATA drive. I have successfully installed GNU/Linux Opensuse 11.2 OS in the new harddrive (Samsung). Besides all that, the other specifications are all stock. After 2 days of successful runs in the new OS and no problems at all, the OS hangs and fails to boot and displays this, Error 18 : Selected cylinder exceeds maximum supported by BIOS. I should mention also that while setting screensaver, when I chose OpenGL, the OS hangs and i have to hard-reset my pc. I suspect that the current BIOS version which is R03-B1 and product name ACRA8000-S03-990610-R03-B1 needed update due to new hardware. But currently there is no new downloads in Acer's website regarding my BIOS version. What should I do to run my Linux successfully? I should also mention that I haven't logged to the internet due to unsuccessful dialer which i have consulted my internet service provider and yet to rectify. (Distributions)
