debian sarge rc1 boot floppy disk doesn't recognize my hard drive

[Edgard Pineda <epineda@newtenberg.com>]

Hello:
	I have an AcerNote Light, without CD-ROM, with a 3com ethernet 3c589
pcmcia card and 1GB of space in hdd (and for now 24MB of ram), I want to
install debian sarge on it, but when i boot this laptop with de boot.img
first, then continuing with root.img and net-drivers.img, the hard drive
wasn't recognized!!
	I test other boot floppy disks of others distribution (FC1, nanobox,
etc.) and the hard drive was recognized without any problem.
	What can I do? I need activate other kernel module?

Thanks a lot in advance for any help.
