thankx, kc00l..
you know what, i got the slackware's GUI ...
by using your last settings in XF86Config...BUT..but...i did somehting i think is hould't have done at this moment.anyways here is what i did and what i got:
1. i reset the MBR ..... and installed LILO.
---------------------------------------------
1.Output1: now my Redhat 9 (kernel 2.4.20-8) is booting off of kernel 2.4.22. which is the slackware's . and it would complain about modprobe couldn't fine modules off of location "/lib/modules/2.4.22" , which doesn't exist , of course. so many of things failed to start (including my modem).
1.Output2. my first hard disk (80gb) is screwed up! none of the partitions show up in the fdisk and fdisk will complain about some error on that disk.
and Windows won't start. and i can't get to my 50g plus data on that disk.
2. luckily, i made a backup of MBR on floppy so,i can get the same old GRUB loader
-----------------------------------------------------------------------------------------------
2.Output1. Redhat loads the way it should , i-e kernel 2.4.20-8. (that's good).
2.Output2. Slack won't, as it used to be before, coz of i don't know what to put in the grub for slack . but for now, i can withstand with that, till my HDD is recovered.
2.Output3. Windows won't load. not good, as i'll loose all my data.
so, as you guys would have figured out, i need help, of course,
for the following:
1. how do i recover my hard disk, with NTFS partitions?
2. how do i copy MBR from floppy to hard disk?
3. this do i put entries for Slackware in GRUB config file?
thanks guys..i'm waiting to see when i get advice howto fix my problems.
