Grub error 15 after removing partition

Greetings, I am hoping someone can help me get Grub working again. My machine was dual boot to Redhat 9 and Windows98. Things were working OK until I removed (using parted) an NTFS partition that was no longer needed. Upon booting, I'm getting to Grub Stage 1.5, when Error 15 is returned. I can boot to Redhat from my boot floppy by passing "linux root=/dev/sda7." I have modified /etc/grub.conf numerous times to try to reflect the partition changes, but the end result is the same. I'm either not understanding the naming conventions or too dense to realize I need to do something else. Interestingly enough, when I run grub and try to "find <fileneame>," grub will find files on the / partition, but not on the /boot partition--I get the same Error 15 returned. Can anyone help? Thanks very much!

Intel PRO/100 M Mobile Connection

Hi! I hope this is the right place; I didn't see a general development list. For that matter, I didn't see a way to subscribe to this one, so I won't see any replies that are just to the list. I would like to install OpenBSD 3.3 (or current) on my Compaq TC1000 tablet. I do not have a CD drive the tablet can boot from, so I am trying to boot bsd.rd over the network using Grub. I compiled Grub (from CVS as of August 16, 2003 -- it claims to be 0.93 in the banner) on a Debian 2.2.20 machine I have access to, like so: ./configure --enable-diskless --enable-eepro100 make Then, I copied stage2/pxegrub to my tftp directory, changed my dhcp config to hand that out to my tablet instead of the previous boot loader I had tried (pxelinux), and tried booting. Grub came up fine except for this: Probing...[EEPRO100]No ethernet card found. It turns out (according to Windows XP, which is what is running on the tablet right now), the tablet has an "Intel(R) PRO/100 M Mobile Connection" Ethernet adapter. However, the driver for this adapter was added to eepro100.c in etherboot after version 5.0.5, when grub last snagged it. etherboot seems to have changed quite a bit (and added a lot of driver support) since then; using what is in etherboot now, I could figure out how to get my particular Ethernet adapter working and supply you with a patch for grub, but I wondered whether there might be an effort to get synced up with all of etherboot sometime soon? Also, are there any licensing reasons I should not copy code from the current etherboot? (And, I'm curious -- why are grub and etherboot separate projects? They seem pretty similar at first glance.) Any other suggestions would be welcome as well. :) I have heard that grub does not boot recent OpenBSD kernels yet, but then I heard that it boots them just like it boots NetBSD; which is true? I figured if there are problems, I will run into them and can fix them then. Brenda
