Message-ID: <13531@sybase.sybase.com> Date: 26 Jun 91 21:29:40 GMT Sender: news@Sybase.COM Reply-To: shawr@sybase.com () Organization: Sybase, Inc. Lines: 17 Hi there, Recently, I got the upgrade bios rom from the manuacturer and tried to upgrade my bios so it will let me define the configure of my new hard drive. However, after I put the new bios in, the system just acted like there is no bios at all. I called the tech support and they told me that I have to reset the CMOS first. I have tried to touch the cmos reset spot on the motherboard, but no luck. So, my question is how to reset CMOS? Disconnect the battery or ... ? And, what is the procedure to replace the bios? (My original bios is two 128k Eproms and the new one is two 256k Eprom. Also, I already adjusted the jumper for the eprom size) Any help will be appreciated! -- rich -- shawr@sybase.com
