[ Please do not use HTML in mailing list posts! ] I am trying to fumble through my first successful install of FreeBSD 4.0. I am installing the OS on a Compaq 2500, with 5 "4.3 GiG HDD" 320MG of RAM and dual processors. I'm not ready to tackle the SMP yet. I am disappointed with the fact that BSD is only seeing 16MG of RAM. Is there an easy way to adjust this setting? All the documentation I have seen references MAXMEM. I was hoping there is a control file that could be edited VS recompiling the Kernel. -- The long and short of it is that you will have to build a custom kernel. For details, see http://www.freebsd.org/handbook/kernelconfig.html Due to BIOS limitations, FreeBSD will only detect at most 16MB or 64MB of RAM. Since you've got more than that, you will have to add the MAXMEM parameter to your kernel configuration. (See the LINT configuration file for an example.) As for SMP, simply add 'options SMP' and 'options APIC_IO' to your kernel config. -- Matthew Emmerton GSI Computer Services +1 (800) 217 5409 (Canada) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
