Weird looking partition table

[Albert DE WINT <adwint pandora be>]

This is what fdisk -l /dev/hda lists:

/dev/hda: 120.0 GB, 120000000000 bytes
255 heads, 63 sectors/track, 14589 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
 
 Device	   Start  Start       End    Blocks   Id  System
/dev/hda1          9151     14589  43688767+   f  Win95  Ext'd (LBA)
/dev/hda2             1      3616  29045488+  17  Hidden HPFS/NTFS
/dev/hda3   *      3745      9150  43423695   83  Linux
/dev/hda4          3617      3744   1028160   82  Linux  swap
/dev/hda5          9151      9163    104391   83  Linux
/dev/hda6          9164     14459  42540088+  83  Linux
/dev/hda7         14460     14589   1044193+  82  Linux  swap

Now, I'm rather confused. 

There seems to be 2 overlapping partitions: 
hda1 and hda5 both start at cyl 9151 ?? Is that OK?

(BTW, I never had any Win95 installed, this is weird.)

/hda3 * is RED HAT 9
/hda6 is Mandrake; I guess (this one disappeard out of GRUB, when I
istalled RED HAT, so I can't boot it anymore)

Any comments would be nice.

Thank you.
