I installed Adaptec aic79xx-1.1.0-rh72.i686 driver on the RedHat 7.2. It can boot correctly with 2.4.7-10, but it can not find scsi driver when boot with 2.4.7-10smp. Does anybody has such experience? Is there any different driver for smp?
I think it doesn't make a difference if it's smp or non-smp, but since you would be running different kernels, you have to install it under the smp kernel as well, so that the installation takes effect on that kernel. Ehmm, but doesn't that driver come already supported in the kernel?, so you would only have to selected and then recompile your kernel, then you don't have to install anything in addition?
I think that driver should support smp and non-smp both. When I install them, two paragraphs displayed,
one paragraph says " .... installed under /lib/modules/2.4.7-10/kernel...". The other paragraphs says "installed under /lib/modules/2.4.7-10smp/kernel..." So it seems that this driver should support both.
But only non-smp can be boot up. I don't know why Because my sytem have two CPU, I think it is better that it can be run under smp kernel.
I never used my computer as "duel" computer. Though, through BIOS setting, I can see that there are two processors there. And when I install RedHat 7.2, it will automatically install two kernels for me. one is 2.4.7-10, the other is 2.4.7-10smp.
Yes, there are only scsi harddisks on this system, no ide harddisk at all. So I have to install scsi drives, otherwise, can not boot at all.
gotcha, my system is similar to your. My two hardrives are SCSI, and my pc is too a Duel CPU.
Okay, here's the best thing to do.
Keep the regular kernel for a single processor.
Then go to www.kernel.org and download the 2.4.19 kernel.
Since kerlen 2.4.17 the SMP is embedded in the same and only kernel, so there is no need for a special "smp" kernel, they are all the same now. So, download the lastest, 2.4.19, and configure it to support 2 CPU's and check on your hardisks SCSI drivers to enable them in the kernel. Then, I can pretty much guarantee you that you'll be running two cpu's and you'll be able to boot as well your scsi hardrives,
there is a very nice How-to Recompile Kernel on this site, , good luck:
zLinuxz, thank you so much! But I am not allowed to change kernel version. We have some programs which are developed base on Red Hat 7.2 and kernel version is 2.4.7-10. So I can not switch to other kernel version.
Is there any good drivers I can download or any bios patch I can get? Current I am using "aic79xx-1.1.0-rh72.i686" drivers. Or I am dead already?
