I **have** installed the new kernel.gz on the boot floppy (it's indeed a GENERIC,
without the SCSI support, without the ata driver, but with the wdc, wd and mcd drivers)
I've make'd the new kernel, compressed it with gzip and installed it on the boot floppy
instead of the "normal" GENERIC.
I've just checked on another machine : this new boot floppy probes and detects correctly
the IDE disks, but /stand/sysinstall complains in the same way

: Hello,
:
: I'm trying to install 4.0 on an ancient machine.
:
: this machine is a VLB 486 PC, with a caching Tekram DC680C IDE controller.
:
: The controller probes fine with "wd" driver, both in 3.4 and 4.0 with a kernel
: recompiled with wdc and wd instaed of the new ata driver (see 3.4 dmesg further)
:
: I have recompiled a new 4.0 kernel on a working 4.0 PC. This kernel has a
: driver for wdc, wdc and mcd, used for the CD-ROM.
:
: The boot floppy boots fine on both a "known working" 4.0 PC and the VLB PC.
:
: The problem is that /stand/sysinstall does not find the wd drives (it complains :
: "no disks found! Please verify that your disk controller is being probed at boot
: time ..." in the second window after selecting a Novice install)
:
: How may I install 4.0 on this PC ? (upgrading from 3.4 to 4.0 with the sources is
: not really an option as the disks are a bit small)
Build your own custom GENERIC kernel replacing the ata stuff with
wd and plunking that on the boot floppy in place of the kernel.gz
that is there.
The quick and dirty way to do this is to:
1) build the modified GENERIC kernel (although it could be more
tailored to your setup) and then gzip it (I usually use
gzip -c kernel > kernel.gz )
2) vnconfig -c vn0 kernel.flp
3) mount /dev/vn0c /mnt
4) cp kernel.gz /mnt
5) sync; umount /mnt
6) vnconfig -u vn0
7) then dd kernel.flp to floppy and see if that helps.
