To run a Data General sniffer on that machine, which uses a rather old version of QEMM, I had to load first MS HIMEM telling it to use the Compaq BIOS call to find the real amount of memory, then QEMM which acquired memory from HIMEM ! > I have compiled the kernel with the line "options MAXMEM=(98*1024)" > included with no success. > On the same machine, Linux 2.0.34 found only 16M, but it was possible to tell it to use 32M at boot time (lilo or loadlin). As I understand "options MAXMEM" may be used to force the recognition of more than 64M, but in that case the kernel is told that the memory is only 16M, so it doesnt look further ???? > Can anyone offer some suggestions to overcome this problem > Avoid Compaq machines ... > Thanks in advance > > God Bless > > David de Jong > -- > ______________________________________________________________________ > |David de Jong | | > |ENERGEX | /\|\ | > |dd026@energex.com.au | / \<---Centre of Universe. | > |Phone +61 +7 34075524(work)| \/ \_/ "Great Spirits Have Always | > | +61 +7 38781363(home)| v encountered violence from meagre| > |Time GMT+10HRS | minds" Albert Einstein | > --------------------------------------------------------------------- > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-questions" in the body of the message > Claude Buisson To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
