XP partitions limit at 1024

[Guest]

When I installed XP Home the disc gave all 110Gb to XP as NTFS.
I then partitioned it with Partition Magic 7. C: was 7.79Gb.
C: is now signaling that it is getting full. There is plenty of unallocated
space to its right.
When I use PM7 to try to expand C: into that space I get an error message
saying,"This partition will cross the 1024 cylinder boundary and may not be
bootable due to INT 13 BIOS limitations".
Is this restriction relevant to XP Home? If so why was there no restriction
before I originally partitioned it?
Can I safely ignore the warning?

Cross post when necessary but please don't multi post, it just creates
more work for every one. Answered elsewhere.

(INT 13 BIOS limitations don't apply to Windows XP, it was a Windows NT
limitation. It was changed with Windows 2000 and up.)
