I am attempting to install RedHat 6.0 on my P233MMX system.
I have a 4.3G HDD for Win98, a fresh (as yet unformatted) 4.3G HDD for
Linux. I also have:
4M VRam 3D video card
56k modem, NE2000 compatible NIC
My problem is the secondary on-motherboard IDE controller. Apparently there
is some kind of IRQ problem. According to Win98 there shouldn't be any
It does say that there is a problem (denoted with a little "!" in the system
properties) with both primary and secondary IDE controllers, yet it doesn't
say what exactly (standard "device is not working properly, or all drivers
are not installed", etc.)
It also says that it is using MSDOS compatibility paging for both.
It assigns IRQ14 to primary IDE, and IRQ15 to secondary, no conflicts with
When I have Win98 HDD and CD on primary, and Linux HDD on secondary, and add
the new HDD in BIOS, the BIOS detects it at boot, but then it hangs, and
eventually says "secondary master hard disk fail."
When I boot from Linux CD (after disabling new HDD in BIOS) and enter
installation, it detects the new drive, but reports these errors:
"hdc: irq probe failed" and
"hdc: lost interrupt"
It eventually continues with installation, and I can set the partitions up
OK. When I select packages and start installing, it freezes up again and on
the other screen (Alt-F4 I believe), it keeps giving that same "hdc: lost
Then I tried putting both HDDs on primary and CD on secondary.
The BIOS still detects CD, but the DOS device drivers don't detect it and
fail to load, and Win98 can't detect it either.
I can still boot Linux off CD. But again it detects the CD, then gives the
"irq probe failed" and "lost interrupt" errors agian.
In the install where it says "Initializing CD", it hangs, and the other
screen keeps giving the lost interrupt error.
I took my box to my local LUG meeting (showed up a little late to really
tinker, only 30mins left...doh), they couldn't figure it out really, and
suggested just using one drive at a time (enclosed-drive swap rack mount, or
switch cable). I would like to have both drives and CD available, and use
LILO to switch boot between OS's.
If anyone has any suggestions please help, post on both ng and email.
